GunTec USA AR-308 Lower Receiver Vise Block
Ratings & Reviews
Very nice snug fit!
by Joshua -
Fits nice and snug with my AR10 and SR25 lowers. No play or slop which means it won't move around on you when tinkering... It is a strong block for sure. My first GUNTEC purchase was a good one.
Good for pistol grip changes
by Clinton -
Haven't used it in a vice yet; but with a test fit I got it to engage through the top of the lower (upside down for pistol grip work) just fine, and it engaged once from the bottom then seemed like it didn't reach because of the logo.
