Badger Mountain Charlie SASS #43172 Posted March 22, 2017 Share Posted March 22, 2017 Having coffee with a friend this morning. In the conversation he mentioned that his AR had an issue with cases sticking and sometimes would not completely eject the spent case. Other than steel cases what could cause this?

Michigan Slim Posted March 22, 2017 Share Posted March 22, 2017 An AR still requires cleaning. Have him get a chamber brush and scrub the heck out of it. Use a good penetrating oil. Clean the bolt too. Link to comment Share on other sites More sharing options...
Michigan Slim Posted March 22, 2017 Share Posted March 22, 2017 ONE of the fixes from 50 years ago was to issue a better cleaning kit............. Link to comment Share on other sites More sharing options...

They chromed the chamber and changed powders to one that burned cleaner. They also actually issued a cleaning kit.

Pat Riot Posted March 23, 2017 Share Posted March 23, 2017 Does your friend have a .223 chambered barrel? Sometimes the hotter Mil-Spec 5,56 rounds get stuck in the chamber as the dimensions are just a little bit tighter. If he isn't sure have him clean the chamber with a proper chamber brush and shoot it again. If it keeps happening his chamber may be a tighter tolerance. BUT you didn't mention what round he was firing. Link to comment Share on other sites More sharing options...

The Original Lumpy Gritz Posted March 23, 2017 Share Posted March 23, 2017 Did it just start doing this? If so, have him check the 2 allen screws that attach the gas 'key' to the bolt. OLG Link to comment Share on other sites More sharing options...

How do we know you ARE the "Original" Lumpy Gritz? plllmmmfff... hey... you could be a Chinese knock-off Lumpy Gritz... Just glad they never named them screws...

Charlie MacNeil, SASS #48580 Posted March 23, 2017 Share Posted March 23, 2017 Cleaning and oiling the carrier is never a bad thing, either. My AR's, if I had any, would be a lot happier running "wet" than dirty and dry... Link to comment Share on other sites More sharing options...

The case of a 5.56 fired in a .223 barrel may show signs of overpressure. Link to comment Share on other sites More sharing options...

Sedalia Dave Posted March 27, 2017 Share Posted March 27, 2017 Best guide I have ever found for the proper lubrication of an AR pattern firearm. As a side note the manual that came with my AR specifically stated NOT to use RemOil. http://www.ar15.com/forums/t_3_7/548967_AR15_LUBE_POINTS.html Link to comment Share on other sites More sharing options...

Also, I had read that using bearing or axle grease on the buffer spring actually helps the quiet it down in operation and slows tube wear. It actually does make it quite. I tried it...just don't do that in a gun used in cold weather. Tried that too - slows things down, causes FTFs and ejection issues. Light Bulb on...Badger, did your friend's problem occur in cold weather and did the gun work normally in warm weather with the same ammo? Link to comment Share on other sites More sharing options...

Completely different set of HS gauges between .223 and 5.56mm. Same goes for .308 and 7.62 NATO chamber. OLG Link to comment Share on other sites More sharing options...

Aeroshell 64 is rated for temps from -73C up to +121C. It contains molybdenum disulphide and is rated for use on heavily loaded sliding surfaces. Be prepared for sticker shock though, aviation greases will cost about $20.00 a tube. But that tube will likely last a lifetime. You could also check with shops that sell Snowmobiles. They can steer you towards other possible sources of extreme cold weather lubricants. Link to comment Share on other sites More sharing options...
