Easy swap of pistol brace (and yes atf, i paid the tax stamp) - Guntec USA AR 9mm Multi Caliber Collapsible Stock

High quality, very positive connections in the detents for collapse and extend, pretty snappy. Mounted easy, heavier than the buffer I replaced should do better on recoil and target acquisition. If the ATF is reading this; HA! It's on my SBR which is properly and legally owned, with a tax stamp as appropriate.
