When it comes to exploring new components and accessories for your AR-15 carbine, a "Mil-Spec" label isn't just an advertising buzzword. While it might lure military gear-o-philes to the checkout counter, the difference between Mil-Spec and commercial components goes beyond marketing. CMC's AR-15 buffer tube kit is a Mil-Spec set of components that add durability and function to your workhorse carbine.

Durability For Days

CMC's AR-15 buffer tube kit is a perfect match for your Mil-Spec buttstock. Its components are manufactured from quality materials like 7075 T6 aerospace aluminum; an alloy specifically formulated to endure the sorts of intense, repeated stress you find inside a working rifle. Nitride finishing and cleverly positioned drain holes keep corrosion at bay in wet environments.


The CMC AR-15 6-position buffer tube kit includes an integrated Quick Detachment point for that high-speed one-point sling you keep adding and removing from your cart. You'll feel high-speed indeed when you've got your one-point sling installed. Never again will your old fore-and-aft sling's ungainly loop catch on underbrush, hang you up on fence posts, or sweep your precious, precious breakfast burrito into the dirt! Add an adjustable six-point adjustable carbine stock to further enhance your weapon's custom and far more handy feel.
