I finally put the 16" stealth barrel I won on my PredatAR. I used a SLR Adjustable Gas Block and it works great. It has a Sandman S that they cerakoted to match the magpul FDE.
Took it out today to shoot various loads and see what it liked the best. This was with 75 Grain at 100 yards. 
(the bottom was 40 grain amax we loaded, not ideal for a 1/8 twist) Its always interesting to see the change in POI with all the different loads. |
