"Outstanding fit, form and finish"

hfloyd_atx on 9/13/2015 11:29:45 AM

Overall Product Rating:


Buy it once, buy it right, buy this and you will not be disappointed. Locks up perfectly. Rock solid platform with so many mounting options. So incredibly light, and strong. It also stays cool, even without rail covers or gloves. The narrow low profile stays out of the way of the charging handle. WIN < WIN < WIN This will mandatory on every G3,91 or PTR I ever own in the future. I could not be more pleased.


"Works on c308 with minor filing."

Overall Product Rating:


Great fit with some ever so minor filing on the end closer to the barrel. The rib on the barrel prevents the end corners from clearing the rib. After 4-5 touches with a fine file, it slid in place perfect. Once it clears, adjust an inner collar to a snug fit. There are three rows of mlok spaces. 3, 6 and 9 o’clock which is all you need for a light, bipod adapter, and a grip.


"This MLOK exudes quality."

This rail is as light or lighter than the slim line surplus handguard. It is strong and essentially turns your PTR into the 21st Century. I did a lot of research and narrowed it down to the B & T handguards or this. You will not be sorry. Here is my video of the end result. Watch the last 30 seconds https://youtu.be/4eZydaha9Mg I would have to say this and the B&T are the best.
