PMAG 20 manufactured by Magpul
These are the best ready to go 300blk magazines available on the market!
These magazines have all the needed internal geometry necessary for cooperating with all 300blk projectiles.
These 20rnd mags are built from the factory with 30rnd springs which help defeat the excess weight of subs, as well as the increased bolt velocities of supers.
Due to the spring chosen by Magpul, these magazines do not need upgraded springs, making these the best 300blk magazines for the price!
NOTE:
WILL NOT SHIP TO BAN STATES. If you place an order for these magazines and your state has magazine restrictions, your order will be cancelled and refunded with a 10% re-stocking fee.
