MEAN Arms - AR-15 Upper Receivers, Magazines, Speed Loaders & Other Gun Parts and Accessories — 25 products / 25 models

MEAN Arms specializes in creating California-compliant gun parts and accessories that allow you to operate efficiently in states and areas with strict restrictions. Their EndoMag magazines are compatible with Magpul PMAG accessories, allowing you to maintain the same efficiency and performance while complying with all applicable laws. We also carry MEAN Arms AR-10 and AR-15 magazine speed loaders that let you safely and quickly reload fixed AR magazines without requiring you to break down your firearm. Beyond reloading needs, MEAN Arms crafts 9mm AR-15 upper receivers with ball-bearing bolt carrier groups that lower recoil impulse for improved accuracy.image
