BudsGunShop.com - Buffer tube size?

Michael, this is a carbine length milspec buffer tube. Have a great day!

Michael, I would get accurate info on the Buffer Tube weight since it is 7.62x29 form Windham Weaponry Customer Service at 855-808-1888

This has a carbine length milspec buffer tube. So any milspec sized stock will fit this. I really like my mission first tactical battlelink minimalist stock, great stock. Hope this helps.

This does include a Milspec buffer tube.

And at the bottom he references the upgraded parts he put on his (with links) and he added the Leapers UTG AR-15 A2 Style Fixed Stock Assembly Polymer Black RB-T469B, which leapers says is compatible with a mil-spec buffer tube.
