Remington 760 / 7600Pump Rifles
Model 760 :
The Remington pump model 760 rifle, called the "Gamemaster" was made with a 22" barrel, was introduced
in 1952 and was discontinued in 1980. It used a detachable 4 shot
sheet metal stamped box
magazine. This model was initially produced only in 300 Savage, 30-06 and 35
Remington calibers. In 1953 the 270 Win. was added. Other calibers added later included
257 Roberts, 244 Rem., 308 Win., 243 Win., 280 Rem., 222 Rem., and 223 Rem.
Initially the wood was plain uncheckered walnut buttstock with a grooved
forearm. These guns were a sales success in that when I
purchased a new one in October of 1954 the serial number was 179,000 and the
price of $109.95, about $5 above the initial price.
The pump action slid on a hollow metal tube that had a spacer
under the front of this tube against the barrel. The ejection port cover
was made of metal, left brightly polished, with the early ones utilizing a
rounded forward outer end, while later ones used the same metal, but slightly
angled to the rear at the front of this cover. These early rear sights utilized a 3/8"
dovetail in the barrel. These rear sights were made by Remington and were
distinctive to the 740 and 760s.
The receiver for the standard 760 was not originally drilled and tapped for either a peep or scope sight. No provision for sling swivels were incorporated on the standard 760 rifle, but were available on the ADL (A grade deluxe) which was also drilled and tapped for scope mounts. Initially there apparently was a B grade, which probably had fancier wood. The BDL replaced the B grade in 1953 and had the same configuration as the ADL but with a more highly figured wood. However you may encounter a ADL with higher grade wood that had flaws in the wood, so instead of scrapping it they downgraded the wood and used it on the ADL models. The buttplate was of aluminum.
To reiterate, the 760ADL version introduced in 1953 which was
the same as the 760 but had deluxe wood, machine checkering, a pistol grip cap
and sling swivels A 760BDL that was introduced in 1966 sported a
stepped receiver rear, RH or LH cheekpiece on a Monte Carlo stock.
Basket-weave impressed checkering was added in the mid 1970s. It had a
black pistol grip cap and forend tip. Made only in 270 Win., 308
Win., 30-06 and 35 Remington. There was a limited run of 760CDL
carbines in 30-06 only and an 18 1/8" barrel.. This model was made only
from 1961 to 1963.
This BDL version was discontinued in 1982.
One confusing thing about the model numbers is that very few actually had the suffix letter stamped on the gun. Also it is my belief that the early Model 760 was just that and when they made numerous internal changes during that first year of production, that the gun after the changes were made then became the Model 760A.
In 1955 the ejection port cover was changed from polished metal to a black plastic, which reduced some of the objectionable rattle of the metal cover.

Later, about 1960 a carbine with an 18 1/2" barrel was introduced but with limited calibers of 270 Won., 280 Rem., 308 Win., 30-06 and 35 Remington. This forearm bracket tube was different than the rifle in that it was composed of two telescoping metal tubes. When cycled to the rear no metal was exposed on the front of the forearm. There was a neoprene O-Ring between the two to eliminate a rattle.
Shortly after the carbine entered the scene, the older forearm support tube as seen in the top photo below was replaced by the carbine style (bottom illustration below) on all other versions.
|Here on top, showing the custom stocked older rifle's forearm tube, with the newer telescoping forearm style below & the later pressed checkering utilizing white lined spacers on the stocks|
What is hard to see on the rifle on top, above is a auxiliary fold down peep sight mounted to the rear of the scope base, hence no barrel mounted rear sight. The lower rifle above uses a Weaver pivot mount so the rear sight can be utilized in a emergency situation.
These guns usually paralleled the 740 and 742 semi-automatics
as far as wood goes, so the impressed checkering on the 742 would have also been
incorporated on the 760 as the buttstocks are the same.
Aftermarket manufacturers like
Uncle Mikes make sling swivel
kits to fit these early guns.
Model 6 / 7600 :
There may have been some confusion with the other Remington #6, which was a
Rolling Block single shot rimfire rifle that Remington made from 1890 to 1933.
When Remington dropped the 760 pump, in 1981 they came out with the Model 6 at a retail of $399.95, which was then discontinued in 1987. This gun parallels the Model 4/7400/74 as many parts interchange. The following year the 7600 was introduced, which is still currently being made.
This newer design has a newer internal design, while still maintaining the same exterior configuration. It was designated model 6, and the Model 7600. The calibers available were 6mm Rem. (discontinued in 1985) 243, 270, 30-06, and the 308. A carbine in 30-06 was introduced in 1988. Again what ever was done for the 7400 was paralleled in the 7600 as for the wood, firing pins reinforced hardened steel insert rail in the receiver, scope mounting hole changes, locking lugs and magazine latch being enlarged. The extractor was changed from the riveted in style, common with the 740, 742, 760 and the bolt action 700 to a non-riveted snap in type. This new style extractor was also incorporated into the model 700 bolt action gun.
The model 6 was the deluxe version (or as the earlier 760 was
designated, it would have been equal to a BDL grade). The Model 6
had high gloss checkered walnut wood with white line spacers under the buttplate, grip cap and forearm tip.
The Model 7600 (would have been equivalent to the ADL) which was the same gun, except plainer wood,
satin finish, pressed checkering and retailing for $50 less than the Model 6.
The calibers available were 6mm Rem. (discontinued in 1987) 243, 270, 280,
30-06, 308, and 35 Whelen. A carbine in 30-06 was introduced in
In the spring of 1982 the Remington factory sales reps told us (independent dealers) that "they" were advertising for the independent dealer and promoting the Model 6 in all national magazines. They were promoting us, the independent dealer. They did not tell us that there was also being made an economy Model 7600. We found out later in the early fall after we got our shipment of Model 6es, that Remington had sold the Model 7600s to K-Mart, Wal-Mart etc. at a greatly reduced price as compared to the Model 6 that they were selling us. The retail customer was not dumb, as he could buy a new Remington pump or semi-automatic 30-06 from the "marts" for $100 less, he did not care what it looked like, only the price, and was discontent that we could not match their (the Marts) discounted price on our higher grade guns. The situation was that the "marts" ordered only the 30-06 calibers, and the customer could not understand why we could not sell them a 270 Winchester for the same price the marts wanted for their 30-06. We were therefore stuck with higher priced guns on our shelves.
Then in 1983 Remington acknowledged, then had the 7600s in their catalog where independent shop owners had to then buy the model 7600's to stay even somewhat competitive. So the model 6's sat on our shelves and at the factory warehouse. It took the factory a few years to figure out what was going on. Beginning in 1990 the high gloss wood of the model 6 was incorporated onto the Model 7600.
As time went on, 1993 and 1994 a Special Purpose gun with non reflective wood, glass-beaded dull metal finish showed on the scene. In 1998 newer versions appeared with synthetic stocked models, glass-beaded dull metal finish. Even later, synthetic stocked models with Electoless nickel dull finish on the metal were introduced.
Model 76 : Then about 1985 there was even a cheaper Model 7600, called the Model 76, made in 30-06 only, which took the place of the "older" 7600, but with cheaper walnut stained birch wood with no checkering. Also the metal finish did not have the higher luster of the 7600. These guns also carried Remington's economy name of "Sportsman".

the hammer is not falling,
or your rifle misfires,
it could be traced to at least 2 conditions (#1 or #2 below).
(1) If someone may have had the
trigger group apart to replace the hammer spring etc., it is possible that the
action bar lock's (#18609) rear tail is ABOVE the tail of the trigger
disconnector bar. The Action Bar Lock is the lever you depress to manually open
the action. Both of these parts are on the LH side of the trigger group, above
in front of the trigger. Under normal conditions, the action bar lock has
to raise up behind the LH action slide bar to lock the pump slide and hold the
rotating locking lugs before the gun will fire. With the ABL ABOVE the
disconnector, it will hold the disconnector DOWN, allowing the gun to fire out
of lockup, or not fire if the operator does not hold the forearm tightly
(2) The early forearms which used the single tube forearm guide, also use a threaded forearm retainer nut very similar to the 870 shotgun. This nut may become slightly unthreaded allowing the forearm to slide forward/rearward on the metal tube, or if you had it apart, it may be that you may NOT have threaded the forearm nut all the way on. If this happens on the old guns, (not the carbines or the newer telescoping action tubes), when you push the pump handle is as far forward as it will go, the bolt may not be totally closed. This is because the older action tube has a pinned in front end cap forming a stop. This then too long forearm nut bumps the end cap, stopping the forward movement of the slide assembly, which does not allow the breech bolt to move far enough forward to lock the action bar up.
As seem in the photo below, for the older models, this forearm retainer nut may come loose. It is tightened in using a split spanner, (or a medium screwdriver) to rotate this nut tighter. It has two slots 180 degrees apart on the front as seen by the red arrows. If this nut becomes loose, it will bump the front metal end (blue arrow), not allowing the forearm metal to go far eenough ahead to allow the action bar lock to lock the forearm in place, timing it so the trigger/hammer assembly unit functions properly.
|Early 760 forearm lockup|
These action tubes screw onto a 3/8 NF bolt protruding from the front of the receiver. The tubes have 3/16" holes in them crossways which you use as a spanner hole (using a #1 Phillips sscrewdriver) to tighten/unscrew the tube from the receiver. You should not have to remove this tube unless you are removing the barrel.
(3) You won't find any specs for the firing pin or spring, as there are
none. If the firing pin is not broken, the length of it is not an issue as
it is a rebounding type, which means when the bolt is locked in position, the
firing pin length/weight/spring tension/ and hammer force are all balanced.
This means that at the farthest forward position the firing pin can be pushed to
and yet be even with the rear of the bolt carrier, it will not protrude from the
bolt face, (safety if the gun is dropped). The force of the hammer
overcomes the light FP spring tension, pushing the heavier than needed firing
pin forward to ignite the primer. The weight of the hammer holds it
forward during firing.
(4) Magazine latches for the model 760 are obsolete, but the 7600 versions
will fit IF you also use the new rat trap spring.
(5) The older guns did not have a metal buttstock spacer installed between the receiver and the buttstock. The newer guns you may see this spacer. What it does is take up the pressure of firing, eliminating the chance of the receiver setting back, slitting the buttstock at the joint line. There should be about a minimum of .010" clearance between the rear of the receiver lip and the front of the buttstock. If yours does not, you might fiberglass it or at least place some kind of metal spacer to protect your buttstock.
(6) If you have to take the barrel extension off to do any rechambering or rebarreling you will need to make a barrel extension wrench. This extension is actually the barrel's locking lugs. It is threaded and timed to the barrel so that the extension is indexed so the sights, barrel lug are all indexed for bolt lockup, headspace so everything where it should be. There is not any commercially available fixtures available to remove these extensions. If you try to use any other method, you will about 99% be assured of breaking the extension. However here is a picture of the one I made.
|Remington barrel extension removal tool|
In the above photo, the inner slider is made to fit inside the barrel locking lugs. The 3/8" bolt locks the slider to the base. The bolt hole is also aligned with the barrel lug attachment bolt hole. In use, for removal the base is inserted over the barrel lug extension, the slider is then slid endwise into the lug recess. The bolt is inserted in just far enough to lock these 2 parts together, but not into the main barrel lug. Mark the relationship of the barrel to the barrel lug with a scribe mark on layout die. This will allow you to reinstall it in the same position.
Remington changed the threads on Feb. 1977, date code (LO), for the 742 and 760, the barrel threads were changed from RH to LH, to help stop the problem of the barrel extension of the 742 (locking lugs) from unscrewing from the barrel during the firing cycle. This was not a problem with the 760, but since many of the parts interchanged, they did the same on both models at the same time. This date code is shown below in the gunsmithing section.
With this change of the threads from RH to LH to facilitate the extension not being backed off when used on the semi-auto guns. This will determine which direction, when you try to remove the extension from from the barrel. You can now put the barrel in a barrel vise, rap the removal handle in the proper direction, then unscrew the extension off the barrel. These extensions are usually on tight and require force to remove even after the initial bond is broken. Once it is off, if the barrel lug is stubborn and resists, you may screw the extension back on part way, do it over again but with the 3/8" bolt thru the lug to take both off at the same time.
(7) Remington has also discontinued making extractors for these guns, #14669 which was 30-06 size riveted type and are the same that had been used on the 700, 740, 742, 760, 788. These extractors are riveted into the bolt, require a special rivet and tool to install. The rivet tool and extractors are currently available from Brownells in Iowa 1-800-471-0015.
(8) Magazine latches are also obsolete. However the latch off the newer 7600 series can be used if the new spring is also used.
(9) Sights have changed many times over the years. If yours is one of the early guns (760) with a 3/8" dovetail, any aftermarket 3/8" sight, both front and rear will fit. If your barrel has the sights screwed onto it like the 742s, you loose part of the rear sight, you might be best to try to get a whole new one for the 7400 or even the 700 series, as the screw holes are all the same spacing. The rear screw on sight has been changed 3 times and parts for the early versions are no longer available from the factory.
About all the newer type pump and semi-auto guns, whether they be rimfire, centerfire or
shotgun use many of the same basic “Fire Control” (as Remington calls the trigger
group) parts. This would be the 552, 572, for the RF, 740, 742, 760, 4, 6,
74, 76 7400 and 7600 for the CF. 11-48, Sportsman 48, 870, 58, 878, 1100, and the
11-87 in the shotguns. They are only supplied in Right Hand from the
factory. You can not simply reverse the RH to make it function as a LH
For many years there were aftermarket Left Hand replacement triggers available from sources like Williams Gunsight Co., Uncle Mikes, Herters, etc. However for some reason these companies dropped production. The guess is that if THEY sold you a replacement safety and YOU installed it improperly, that they were responsible legally because they SHOULD HAVE KNOWN that someone could also done something else wrong inside the “Fire Control” unit at the same time, creating a unsafe situation These companies also felt threatened by lawyers to the effect that they were making a product that altered the factory design.
Buttstock wood is the SAME and interchangeable for all of the Models 740, 742,
#4, #6, 74, 7400, 7600. Forearms from the 7600 should fit the late
telescoping style forearms of the 760.
