just your standard AR10 carbine buffer tube

by -

This is a good quality buffer tube combo. Not much more to say about it, its a simple milspec buffer tube, a nice spring that seems to dampen noise well, a standard buffer, a castle nut and a standard endplate. Everything fit and functioned just fine, not much else to say.
