More Remington 870 problems

deerhuntertyler · 10-22-2009, 07:23 PM

OK, I have sold both of my 870s and got some benelli novas because of problems with them jambing but my dad still has his 870 12 gauge because he does not want to spend money on a new gun right now. But last Sunday when we shot are guns to prepare for shotgun deer season, his chamber came open every time he shot. We only shot it four times because we dint want something to really go wrong but when you cycle the empty shell out and the new one in it did latch in and would not come back but when he shot the chamber and pump came 1/2 way-all the way open. I cleaned the gun extremely thoroughly including taking it all apart and cleaning everything hoping that would help but we tried shooting it again and the 2 shots we fired had the same problem. I'm no gunsmith and don't know whats going on so any help would be appreciated.
thanks, Tyler

I have several 870's and they all do that, are they designed to be that way? if the bolt locking mechanism was not released by the recoil you would have to push the locking release button every time you shot a round, just like emptying the chamber of an unfired round.. Is there something wrong with your gun or your dad's gun. Are you holding on to the forearm when you shoot? or are you shooting of a rest and not holding the forearm?? That could cause the problem you are having..

And I have several Rem. 870,s and mossy 500,s and other model pumps and none of them fly back.When the barrel is the right length to allow the damn bolt lock to fully enguage they dont fly back. ,,,sam.

So, is there something wrong with my 870's also?? My friends also does this, is it hurting anything or are we alright to keep shooting them, I have been shooting them for years this way..

It has been my experience that well worn 870's will do that IF you do NOT hold the forends while shooting. Check the locking block on top of the bolt and check the notch in the barrel where the locking block goes into. Make sure that it is clean. Make sure the slide, which rests on the action bars beneath the bolt, is in good order. That makes the locking block go up and down when it goes back and forth. If that is damaged, the locking block will not go up all the way. The notch in the barrel where the locking block goes into might be peened over or worn. Remington will tell you to just send it back. Take it to a gunsmith and have them look it over. Make sure every part is clean first, that is the cheapest fix sometimes. Let us know.
Take the weapon and make sure that it is empty, check it again. Work the action and cock the gun. Hold is straight up, not holding the forend, and pull the trigger. The slide should go just a bit back. Well worn 870s will go an inch or more when you do that. Action bar lock could be bent or worn also. That is the part that locks the action bars until the gun is fired. Slide release button in front of your trigger guard, all the same piece. The other end of that locks the action bars. That could be bent in or worn. Could be just a weak action bar lock spring.

I have owned several 870's and have one now for self-defense.
I have just never had a problem with any of them.
I do give a solid push and pull for operating the mechanism.
I am not saying jam it forward with all your strength. Just give it a solid push and I have found mine to lock up all the time.

None of the 870s I have owned or currently own pop open when fired. Now I had a winchester 1300 that did that but it was supposed too.
