AR-15/M16 MIL-SPEC BUFFER TUBE 6 POSITION Reviews & Ratings

AR-15/M16 MIL-SPEC BUFFER TUBE 6 POSITION

Brownells AR-15 Mil-spec receiver 6 position extension tube has the correct 1.148" outside diameter to ensure proper fit of adjustable mil-spec carbine stock. Allows you to install a mil-spec stock on a commercial carbine, convert a rifle with a fixed A2 style stock to an adjustable M4 stock, or complete a custom build. Six machined notches on the underside prevent the stock locking pin from slipping, yet still offer outstanding ease and flexibility in setting the buttstock length. Precision machined from strong, lightweight 7075 aluminum, then hardcoat anodized with a hard, wear-resistant matte black finish.

Appears to have been dropped
Buffer tube was packaged in a zip lock bag along side the glock magazine witch was in a factory blister package inside a padded envelope. Buffer tube had broken through the envelope during shipping causing it be dented through the finish on the rear edge. It was to much trouble to return it so I decided to go ahead and keep it because the dent would be hidden under the butt stock, but I don't like to pay full price for an item that is not perfict. The order should have been packaged better.
Would you recommend this? Yes, I would recommend to a friend

Functional but roughly machined
I used this for a while on a build and it functioned fine and appears to be machined straight. The threads also timed well with multiple lowers I have. However the inner bore has a very rough finish that led to excessive buffer noise and a very unsettling gritty feeling as you pull the charging handle back. Greasing the buffer spring barely helped at all, and shooting the rifle a few hundred times also didn’t help much. I finally just replaced it with a BCM tube and that solved all my problems. Overall it’s good because it’s functional and it’s priced lower than most others. However given how much this one part negatively affects cycling smoothness, I just don’t think it’s worth it. Unless there is some kind of crazy discount and they are practically giving these things away I would suggest getting a VLTOR or even a aero precision tube over this.
