Description
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 Arms and buy with confidence.
Includes:
- Mil Spec 6 Position Buffer Tube
- End Plate
- Castle Nut
- Standard “H” Buffer 3.9oz
- Carbine Buffer Spring for Collapsible Stock
