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. The Mil-Spec buffer tube is made from aluminum and the recoil spring is made from stainless steel. When paired with a carbine length gas system, this buffer assembly will provide exceptional reliability and durability. The enhanced buffer tube also has a lip on the bottom that extends further into the lower receiver, providing more strength to prevent it from breaking. Simply thread it into any Mil-Spec AR-15 lower receiver and is compatible with a large variety of aftermarket buttstocks. The included castle nut and lock ring ensure that the buffer tube will not back off over time. It also includes a QD receiver end plate for attaching your favorite sling. The spring and buffer weight are tuned specifically to .223 and 5.56 caliber rounds and will not work with .308 rifles. Finish your AR-15 build with this complete buffer tube assembly today.

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

Great kit! Buy without worry...

by -

CMC made another excellent quality part with this buffer tube kit. Fit and finish are tremendous and I also really like that they chose to include a QD style end plate which is how I run all my slings. Buy without hesitation...

A good product at a good price

This is a good product. I have had no problems with it at all. I like the one-point sling attachment. Recommended (and on sale now).

QD end plate won't work with Magpul PRS Gen III buttstock

by -

This does function, and it's ok, at best. I had a bit of an issue keeping alignment, and getting detent spring in, and then recoil spring detent. The big problem arose when I purchased a Magpul PRS Gen III, looked easy enough to install but when I slid it onto the tube, it would not seat against the castle nut because of the QD mount style end plate. Thankfully I had another end plate, but trying it, it then took 30 minutes to get proper alignment again with both of the previous springs/detents. I'll be the first to admit I'm not an expert but I've installed more buttstocks than I can recall and never had this issue. I suspect there are other fixed buttstock kits that would not work because of this as well. Even though I go this to work, I'm replacing it, it will go in my "in case I build a cheap AR pile".

Dissapointment

by -

Purchased a few months back, just now got around to assembling lower. POS ALUMINUM CASTLE NUT. Broke when I put about 1 1/2 ugga duggas on it. Disappointed to say the least. Rest of product seems fine.

Don't Buy!!!!

by -

Should of read the reviews before buying. The buffer tube and end plate are out of spec. My magpul stock gets stuck on buffer tube when adjusting. Magpul QD attachment doesn't fit the end plate. Will be changing both buffer tube and end plate soon.
