| AR-15 and M-16 mags are interchangable right? Ive gotten a few conflicting answers on it believe it or not. As far as I know the only differances are the tolerances and the trigger mechanism. |

Quoted:
AR & M16 mags are one and the same. yep, no differences what so ever..... and sence it is probably the most used mag out there many other guns use it too ie..... the FN SCAR Sig 556 Bushmaster ACR XCR FN F2000 and newer versions of the Steyr AUG are just a few |

Quoted: AR-15 and M-16 mags are interchangable right? Ive gotten a few conflicting answers on it believe it or not. As far as I know the only differances are the tolerances and the trigger mechanism. Not sure what you mean by tolerances. Most AR-15 lowers were at one time cut from Armalite and/or Colt's original lower dimensions (according to posts in ARFCOM), but today, there's variances all over the place. It almost doesn't matter a whole lot because most manufacturers will make sure the magwell will fit the most common brands of USGI & polymer magazines - this is with respect to the magwell dimensions only. With respect to the outside dimensions, its both cosmetic and functional/strength. With respect to the inner dimensions, its more precise but there's AR's with and without the "lower shelf" for a RDIAS, amongother things. Last but not least, an M-16 lower has one more set of holes cut thru the body, just above the safety selector...to hold the pin for the auto-sear. As for the trigger mechanism, there's more differences than that. The M-16 uses a different bolt carrier and the chamber/barrel are 5.56 whereas not all "AR-15 style" barrels are. (BUT THIS IS A DISCUSSION FOR THE NFA FORUM, and doesn't belong here.) As for mags, they are for the most part interchangeable...as long as you go with a well-known brand, make/model. Then again, it soemtimes depends on yoru brand lower. I've read on this site about some well-known brands of lowers that just don't fit certain brands of USGI and/or polymer mags. For instance, I have 5 pre-ban fully functional & working DSL/Sanchez mags that just won't slide in/out easily into any of my 5 Rock River lowers, but they slide in/out/drop free from any of my 5 Bushmaster lowers, 3 Deltons, and 3 LAR lowers. And to add to the confusion, all of my C Products, 2 PMags, and 2 Lancers all slide in/out/drop free just fine in the Rock Rivers lowers. |

Quoted: Not to add to any confusion but I thought i would add that the M-16 mags would also work in PRE-ban Mini-14s, now they have to have there own mags....Dam politicians.  SASS No. A Mini-14 mag made in 1980 will work in a current rifle and vice-versa. Standard M16/AR mags never did. There were a couple of plastic abortions made in the 80's that were advertised to work in both
