Magpul Original Equipment (MOE) carbine buttstock provides the quality, durability, and ergonomic benefits of Magpul’s CTR stock in a rugged, economical, drop-in package. Strong, A-frame design is lightweight and comfortable, yet provides operator with plenty of support. Comb contour is wider than standard issue M4 stock to help shooter maintain a solid, consistent cheekweld. Streamlined exterior and protected release lever won’t snag on clothing, gear, vehicle interior, or vegetation. Heavy duty, spring-loaded release lever allows fast length-of-pull adjustments and won’t dig into your hand. Impact- and heat-resistant, polymer construction includes molded-in reinforcements at stress points, plus two slots for web slings and a hole for a toe-mounted sling swivel or clip-on sling. Soft, synthetic rubber buttpad increases comfort and helps prevent slippage. Mil-Spec fits 1.14" O.D. buffer tubes on Colt-manufactured M4 and similar mil-spec tubes that accept both four- and six-position collapsible stocks.
