cody6.0 Posted January 2, 2010 Share Posted January 2, 2010 Quick question guys how tight are you turning the PG stock onto your M4? I only ask because following the manuals "max one turn past meeting the reciever" is firm but lets it move just a bit firing even birdshot.

StrangerDanger Posted January 2, 2010 Share Posted January 2, 2010 Hand tight until the last rotation. I then back it off to position. Any looser and it shifts around. Quote Link to comment Share on other sites More sharing options...
Unobtanium Posted January 2, 2010 Share Posted January 2, 2010 If you over-tighten it the trigger group won't fit in very easily. Tighten it until it is funky to install the trigger group*, and then back off until it's not. The trigger-group will keep the stock from doing more than just shifting a little anyways. Very intelligent design. *Please don't get stupid with it. Not saying anyone posting here would, but it just seems that a disclaimer is warrented when a tq-spec is not given.

cody6.0 Posted January 2, 2010 Author Share Posted January 2, 2010 I don't really want to go all OCD or over think this but heres what I got. If I hand tighten it with minimal effort it stops with the PG facing up. - To get it in position by tightening it requires a bit of force. - To get it right by backing it off means it moves a few mm after shooting. When I say it moves it by no means is a large amount but enough that the trigger guard isn't flush with the stock tab and it bothers me. On my SNT& M2 I always made sure the seams were lined up so is this "looseness" normal or is my OCD getting the best of me? Quote Link to comment Share on other sites More sharing options...

cody6.0 Posted January 3, 2010 Author Share Posted January 3, 2010 So run it home or deal with the slop? Quote Link to comment Share on other sites More sharing options...
Unobtanium Posted January 3, 2010 Share Posted January 3, 2010 So run it home or deal with the slop? Can you install it with no wiggle and still get the trigger-group in? Quote Link to comment Share on other sites More sharing options...
cody6.0 Posted January 3, 2010 Author Share Posted January 3, 2010 With the stock 100% tight to where it moves neither way after a shot the trigger group is a just a smidgen tighter. Quote Link to comment Share on other sites More sharing options...

texas skeeter Posted January 3, 2010 Share Posted January 3, 2010 Then do that. or just put "blue locktite" on the threads and let it cure once your in the position you need. Quote Link to comment Share on other sites More sharing options...

Not saying anyone posting here would, but it just seems that a disclaimer is warrented when a tq-spec is not given. When I was a machinist the standard smartass answer was: "Tighten it until the threads strip or it breaks...then back it off a quarter turn!":rolleyes: Quote Link to comment Share on other sites More sharing options...
cody6.0 Posted January 4, 2010 Author Share Posted January 4, 2010 Well I just ended up going with the damn good and tight method. Without that last turn even birdshot would boom enough to move it and I cannot deal with that. Too bad the PG stocks don't fit as well as the standard straight stocks because this wouldn't be an issue. Quote Link to comment Share on other sites More sharing options...
