The Toms Tactical AR-10 308 Carbine Buffer Tube Assembly Kit is 100% made in the USA. This kit allows for the use of a collapsible stock on your 308 carbine. The mil-spec buffer tube is manufactured from 7075-T6 aluminum and features hard coat anodizing. The 7075-T6 aluminum tube is nearly double the strength of 6061-T6 aluminum found in most other “mil-spec” and commercial buffer tube variants. The castle nut and end plate are made of steel, not aluminum. The 308 buffer spring length is 11.5 inches. The 308 carbine buffer is 2.5 inches. All Tom's Tactical brand products include a lifetime warranty.  

Works with any DPMS style 308 AR-10 and Aero Precision M5.

Parts Included:

  • Mil-Spec 6 position Buffer Tube (7075-T6)
  • Steel Receiver End Plate
  • Steel Castle Lock Nut
  • 308 Buffer Spring 
  • 308 Short Carbine Buffer - 3.8oz 

Built a .243 Win & had feed & stovepipe issues. Determined the buffer was too heavy & spring too tight. Purchased & installed this set & problem was fixed. Fast shipping, good price.


I replaced an A2 stock on my PSA P10 Mod2 18" SS mid length with this buffer tube kit. Took it to the range and it cycled perfect! No issues. It ejected the brass at the 3 to 4 o'clock position! I'd highly recommend this kit if anyone is shopping!


Works well with my Aero Precision M-5


Great product. Everything I wanted shipped fast at a good price.
