CMC Triggers AR-15 Buffer Tube Kit - Carbine

Looking to build the ultimate AR-15 carbine? This Mil-Spec carbine buffer tube kit from CMC Triggers comes with everything you need to attach a collapsible 6-position carbine stock to your AR.

Features:

• Carbine-length aluminum extension tube
• Standard .223/5.56 rifle stainless steel buffer spring
• Standard .223/5.56 buffer weight
• Castle nut
• Lock ring
• Receiver end plate with QD sling swivel slots
• 3 oz weight

The enhanced buffer tube has a lip on the bottom that extends further into the lower receiver, adding strength to help prevent breakage, and threads into any Mil-Spec AR-15 lower receiver, compatible with a large variety of aftermarket buttstocks. The included castle nut and lock ring ensure the buffer tube won't back off over time.

Note: the spring and buffer weight are tuned specifically for .223/5.56 rounds and will not work with .308 rifles.
