Adjustable for your arm length and the adjusting screw stays tight. Comfortable fit. Very well made. Bought the "1 inch lowering block" for better mask clearance and it worked great. I also bought the "intruder bottle foregrip" to push my air tank 3-4 inches forward. It gives you much better clearance for your stock and makes it more comfortable.
Adjusts for your arm length, comfortable fit, with the 1 inch lowering block it gives good mask clearance. Very good product. Well worth the money. Highly recommended
That is strange. Because mine has a tendency to collapse when I'm firing it . Even though the bolt stayed tight it still collapsed. Maybe I have a defective one . Let me know if anyone else have this problem.
