Okay but there are issues - Fortis Manufacturing SWITCH 308 Mod 2 Rail System

Pros: Light weight, easy on/off, looks.....

Con: Won't maintain a zero, shifts fro center line.

Okay, for the price this thing should be able to maintain zero. I turns out to be more gimmicky then functional. Mounting a front sight on it will be fruitless as the guard shifts with relative ease and slight pressure. Forget about mounting IR lasers or visible lasers on it. It would fail at hog hunting at night and certainly would not hold out to hard use or military/duty use. I am actually really disappointed in the product considering the price I paid. I fully expect a solid lock up on the hand-guard at this price point. The good part is that since I am running a .308 having an adjustable gas block is essential (IMO) and there is a convenience to quickly taking off the guard to adjust it. Only thing is, there are only so many times you need to do this and maintaining zero has precedence over access. Loosing zero without even taking it off is bad enough but you definitely loose zero when you take it off and put it back on. While it is on very little pressure is needed to push/pull away from the barrel causing a shift which will destroy your zero. If access to adjust gas block is a concern then save your money and buy an extended reach tool/gas-key to make adjustments and buy a more solid mounting guard. Now, that said, this thing is light and on a .308 it is very beneficial if weight saving is important but I just think there are still better options available especially in this price range. I have torqued this down, even past Manufacturer specs. and it still shifts so short of stripping screws and damaging the product I will reserve it for scope only setups when forward zero is not an issue. Recommending this product only because it may still suite some peoples purposes and it is very light weight and very easy to operate. Just don't expect to maintain any confident zero with front iron sights or lasers.
