Hey guys, I know the Bryon is busy so I am gonna see if some of you guys can field this Question for me. I was taking apart my LCD mount (neilson device) to clean it yesterday. I got the back off and the spring came out but the actual stainless part that threads onto your barrel would not come out. It would only go about half way then stop. it would not come out the front where I unscrewed it with the tool it came with the spring came out but no joy on the piston or whatever it is called. So I am wondering if it only going halfway then stopping if it is working correctly... I mean moving far enough forward to allow the gases to enter the can from the LCD instead of following the bullet. so Any input here guys?
