While you have the handguard off be sure to check the collar that holds the handguard.I have a T3x TAC1 in 6.5cm. The forestock , I discovered would wiggle up and down. The 2 hex head screws that holds it were tighten as tight as possible until they finally stripped. I was able to remove them and take the the forestock off. my problem now is how to put it back on and securely tighten it where it won't wiggle.
Any ideas?????
I've seen a few people post that it was the screws that hold that collar that was loose causing the problem.
