I have a AR15 seems to be more accurate the dirtier it gets, as soon as I pull it apart and clean it, it shoots all over the show. Pulled it apart to put a wedge in it, didn't clean it and was really accurate, gave it a clean and turned to shit. Any ideas on why it would be doing this and any suggestions to keep it accurate please.
Thanks
Do you clean the barrel? If so, to what degree?
All I do is put alittle oil on a cleaning mop and pull it through the barrelQuote:

The last time it took around 40 -50 before it came right, this time have only put around 30 through and still not shooting straightQuote:

Can you take a few pics of your bolt head from the rear and front.
Or better yet you could just try another bolt head and carrier if you can borrow one somehow.

Define 'accurate' and 'turned to shit', just to put a scale on the problem
Ok when its shooting accurate its grouping within the size of a golf ball, when its turned to shit it groups in the size of a basket ballQuote:

Ok I am using M-PRO 7Quote:

No problems for me using M Pro 7 in my AR. Works like a charm and groups nice and small. (Golf ball size to me).
Are you removing your optic to clean the upper?
If I had a rifle like that I would give it to my wife so she could learn from its example.Quote:

I presume that after you've "cleaned" it you use a dry patch before you fire it again?
I use synthetic oils like M-Pro 7,Breakfree CLP and Tetra Gun in my AR15 and Mini 14. The most important thing is to dry-patch the barrel before shooting, to prevent an oil ring bulge.
Even a slight bulge can ruin your accuracy...speaking from experience!
Most rifles take about half a dozen shots to settle down and shoot their best after a thorough cleaning. But 40 shots sounds excessive.

Interesting, but I doubt his client's possess the skills to notice any accuracy losses. It's a 10m range in loss Vagas, most clients just want to fire a few clips on full auto so they can post a photo on Facebook.Quote:
