dannycreasy,
I've never known EXACTLY why (I'm not a gunsmith.) but my 1953 & 1954 Model 760 rifles do NOT accept many of the magazines that the "experts" say that will fit the early rifles.
(My "extended magazines", that hold 10/15 rounds & DO fit my "early rifles" were made by POLICE EQUIPMENT COMPANY & sold by GEORGE F. CAKE COMPANY of Dallas, TX. Those are REALLY NICE quality magazines but NOT cheap to buy., I paid 50 bucks for my 15 round magazine.)
Note: Police Equipment Company reportedly made some 20 & 30 round magazines, in the pre-1960 era, but I've never seen any of those. - I have seen photos, so I presume that at least a FEW were made.
The post 1950s Model 760 rifles/carbines GENERALLY will accept ANY magazine that was produced by Remington & SOME "aftermarket" magazines..
yours, tex
