I might catch a lot of flack on this one Mike, but I wouldn't recommend any type of loc-tite with AG's. A tuned rifle will rarely cause loosening of most bolts/screws on an AG. If you tighten any mount sufficiantly to the DT/rails, then a periodic inspection is only needed,...like if your accuracy starts to waver. Same goes with the stock screws too. I've replaced the factory stock screws in a few of my rifles with allen head bolts which will give you a tad more torquing than the phillips screws. A scope stop or a one piece mount with a scope-stop pin will be your best bet. Best Wishes and Happy Shooting!!!! tjk
