I just received my new Sniper 370 and am trying to adjust the foregrip. Loosened the screws on the foregrip, but it won't move. Took the screws all the way out and it won't move. I am wondering if it is still adjustable. I thought the scope was a lighted reticule, but that no longer is the case. So I was wondering if the adjustable foregrip has changed too. Would appreciate any help. Thanks
