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.
With roots in aerospace manufacturing, CMC is perhaps best known as the producer of the original drop-in precision trigger for the AR-15/10 platform. CMC Triggers are dedicated to crafting the finest parts and accessories for law enforcement, military, and civilian use.

Don't Buy!!!!
by Ricardo -
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.
Dissapointment

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.
QD end plate won't work with Magpul PRS Gen III buttstock
by Doug -
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".
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).
Great kit! Buy without worry...

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...
don't bother
by daniel -
not worth the money don't waste ur hard earned dollars totally out of spec. end plate chase is 10% out of alignment with the recoil spring catchment tab which is 10% further off from the end plate chase
