Buffer Tube for Pistol Build by Moose, April 14, 2020
Vltor makes a great product. Fit and finish was as expected. I didn’t need the end plate (using a Magpul with QD mount) but well worth the price. Fit on a Sb Tactical pistil brace with little movement. Shipping took a few days longer due to COVID-19 ...
