Default AR7 Issues

I having super issues w/ my AR7..Fires one shot, wont recoil to eject and feed in a new round. So basicly its me working the bolt manually. Besides a good cleaning does anyone know of any problems an Armalite AR7 has that causes this?

I had one a few years ago and had a few problems with ejecting and it shooting three or so rounds with every trigger pull. Yes, I good scrubdown would be first. Make sure you clean out the area on the barrel that the extractor sets into, if there is enough garbage in there the claw may not be able to grab the rim properly. Check and make sure all your internals don't have any abnormal wear or even chips in the metal, especially the bolt face.

Take a look at your recoil spring and rod, could be bent not allowing the bolt to cycle properly under fire. What type of ammo are you using? Some weak ammo like .22 Short and .22 Long probably won't cycle the bolt.

Heck, Its just a huge can of ammo. I dont even remember the brands (just dumped about 4 bricks into an ammo can) but I too was told they are ammo picky. Not a good thing for a survival rifle..Im surprised at the problems Im hearing about, and having w/ this weapon. I guess that might be why the Military stopped using them long ago...

Thanks for the tips.....Ill run down the list you mentioned..

I still have my faithful M6 Scout though!:D

Default AR7 Fix

Good morning,
I have these come into my shop frequently. It is a rather easy problem to solve. The feed ramp comes from the factory with a too steep or nonexistant angle. This causes serious FTF and FTE problems. You will need to chamfer that ramp. A quick, 5-minute fix is to take a rotary tool with a felt pad coated in #5 or #6 polishing compound and polish that feed ramp mirror smooth, while chamfering the edge. I will work the entire lower half of the chamber rim that you can see on the rear of the barrel assembly. Seems to work everytime! God Bless! Jerry

This might be a very good way to fix a failure to feed but the problem is a failure to eject , it sounds more like something is preventing the bolt from going back, low power ammo, maybe a kinked spring , substituted too heavy springs, no lubrication , accumulated powder residue and carbon. A schematic is available here http://stevespages.com/page7a.htm look under ARMALITE . A manual is here http://stevespages.com/page7b.htm look under CHARTER ARMS AR-7 EXPLORER. I would start there before I took a DREMAL to the feed ramp. After you get it ejecting and if you have a feed problem then try the feed ramp polishing.

The M6 scout is the heat. Ugly gun but cool as snot. Something about it makes you want to go hang out in the woods for weeks on end.
