Rainier Arms Milspec Buffer Tube Kit

Rainier Arms Milspec Buffer Tube Kit

Availability: In stock




The buffer tube we sell in our kits are made from 7075 aluminum with dry lube finish (100% milspec). Don't be fooled by other companies selling milspec tubes made from 6061. It might be milspec in size but it's not truly milspec. Buy from Rainier and buy with confidence.

If you were to purchase the items separately, it would come out to be $84.90. You are getting the kit at more than 15% savings.


  • Mil Spec Buffer Tube 7075 aluminum

ExcellentReview by Brett L.
Just like it's stated in the detail section, this thing is Mil-Spec to the "t" and has a nice tight tolerance to my B5 Systems Enhanced SOPMOD stock. Absolutely love it. (Posted on 5/26/2016)
