Sleepswithdogs Posted October 1, 2012 Share Posted October 1, 2012 (edited) Took my new AR to the range today, shot like a Abrams in the desert. Have a couple of small changes to make but all in all, I'm more than satisfied. Had one small problem, bolt wasn't locking back, but it was easily cured with a 1/2 turn open on the gas block. I did have one big problem, it's doubling. Not just once or twice but out of 40 rounds doubled 4 times. I took to loading 1 round at a time it was so bad. I think all I have to do is re-adjust the sear on the trigger, (it's a JP EZ installed by me) but if there is anything else I need to look at, I sure would appreciate a heads up. I already have the red locktite supplied by them, on the threads and have some left over, also have some blue locktite. Guess I'm going to have to get out a small torch to get the red loose, Not sure which I should use red or blue when I re-adjust it, guess I'll decide after I try and get that tiny allen loose. Any advice, comments, suggestions would be greatly appreciated. Thanks in advance, Tar Edited October 1, 2012 by Sleepswithdogs Link to comment Share on other sites More sharing options...
twodownzero Posted October 1, 2012 Share Posted October 1, 2012 Is there an overtravel adjustment? If so, give yourself a little more overtravel. Link to comment Share on other sites More sharing options...

Yes there is, and I hadn't thought of that. I'll give it a try first, thanks. Tar Edited October 1, 2012 by Sleepswithdogs Link to comment Share on other sites More sharing options...
caspian guy Posted October 1, 2012 Share Posted October 1, 2012 Yep entirely possible that it is bump firing. A bit more overtravel would help wit that. Link to comment Share on other sites More sharing options...
Don Springer Posted October 1, 2012 Share Posted October 1, 2012 I slapped some yellow JP springs in a rifle once and wasn't paying attention to what I was doing. Put the springs in wrong and started to get some doubling. Also had problems with reset. Take a look at your springs first. Link to comment Share on other sites More sharing options...
Sleepswithdogs Posted October 1, 2012 Author Share Posted October 1, 2012 (edited) I'll look at the springs again Don, thanks. Tar Edited October 1, 2012 by Sleepswithdogs Link to comment Share on other sites More sharing options...
Sleepswithdogs Posted October 1, 2012 Author Share Posted October 1, 2012 (edited) Ok, I got it to fail a safety check, had the hammer drop when I release the trigger, so the sear engagement is just barely out. Now I'm not sure what to do, tried to move the allen set screw and couldn't cause it has the red locktite on it. Hate to take a torch to that tiny trigger, think it could easily warp. Any suggestions? Soldering iron? Thanks, Tar Edited October 1, 2012 by Sleepswithdogs Link to comment Share on other sites More sharing options...
Shooter115 Posted October 1, 2012 Share Posted October 1, 2012 Try a small butane torch. Should be able to provide the heat needed without any trouble. Keep light to moderate torque on as you give it a little heat and it should pop way before you warp anything. Link to comment Share on other sites More sharing options...
caspian guy Posted October 1, 2012 Share Posted October 1, 2012 Could try the tip of a soldering iron applied directly to the screw. Link to comment Share on other sites More sharing options...

Thanks guys, think I can get either of those for about $10. Link to comment Share on other sites More sharing options...
Dan Sierpina Posted October 1, 2012 Share Posted October 1, 2012 If the hammer drops while releasing the trigger, the disconnecter timing is off. It's releasing the hammer to soon. Link to comment Share on other sites More sharing options...

Ya, that is my fault. Guess I set it a hair thin, now I need to break the red Locktite loose from those tiny, tiny allen screws. Guess my options are soldering iron or small butane torch. If you know of any other options, I'd sure appreciate hearing about'em. Thanks everyone, Tar Link to comment Share on other sites More sharing options...
wideerhunter Posted October 1, 2012 Share Posted October 1, 2012 I sent 2 lowers to JP and had them do the installs. That's always an option for you as well. Link to comment Share on other sites More sharing options...

You can get some "Heatstop" from Brownells. Link to comment Share on other sites More sharing options...
Sleepswithdogs Posted October 1, 2012 Author Share Posted October 1, 2012 Ok, I don't do man crushes, but, just bought a BernzOmatic micro torch... WOW was that cool. Blasted that locktite out like nothing!! And all for the princely sum of $10 bucks!! Now to re-install the trigger. Thanks for the help, it is much appreciated Tar Link to comment Share on other sites More sharing options...
Shooter115 Posted October 1, 2012 Share Posted October 1, 2012 Yep. That's the one I meant. I've got the same one, just couldn't remember the brand. It's a handy little tool. Link to comment Share on other sites More sharing options...
Sleepswithdogs Posted October 1, 2012 Author Share Posted October 1, 2012 Amazing one can buy something like that for $10. Sure got that locktite out in a hurry, with no fuss, no muss. Have the trigger all re-adjusted, and hope the problem is solved. Thanks again, one and all. Tar Link to comment Share on other sites More sharing options...
