Not locking is normal.
Locking back is not. Without a mag. Not a problem though. When you pull the charging handle push in on the bolt release at the bottom to lock it back. |

I haven't ever experienced this issue, so I can't tell you the solution.
However, some more information would be helpful. Can you look through the ejection port while you try to lock it back, and give us an idea what you see? You should see (and feel) the catch come up once the bolt and carrier clear it, then watch as you ease the bolt forward to see if the catch didn't come up far enough, or if the catch is somehow pushed down by the bolt. |

Do you mean after the bolts locks to the rear WITH a magazine and you take the mag out, the bolt doesn't stay locked?

You are pushing the bolt catch, right?
If the mag will engage teh catch, there's no reason your finger pressure wouldn't. are you sure you've presented all the info? BTW, I may be coming off as a dick, but presuming your BC is complete, I can think of no reason it wouldn't work manually. |

When I remove the magazine the bolt will close most of the time (I would say over 90%) and the few times the bolt stays open I happen to lightly hit the rifle against any surface, the bolt will go foward.
Please remember this is not happening to my Bushmaster or DMPS rifles. |

Is the spring in the bolt catch harder to push in then your other rifles?

With my finger pressing the catch it will not hold the bolt back. I did swap the bolt carrier with my bushmaster and DPMS and the results were the same. Do you guys think there is something wrong with the magazine catch? |

Yes, it sounds as if the bolt catch/release is not right.

I'd try a new bolt catch assembly (catch, spring, detent, roll pin) and see if that fixes it.
I'm sure if you call RRA they would send you the new parts. If the rifle is out of warranty it might cost a few bucks, but worth it to have a functioning rifle. |

I ran into a problem with a friend's rifle like this. You could push the bottom of the bolt catch in to lock the bolt back and it would barely catch. I bet if you breathed on it would go forward. Never got a chance to look at it closer but I did tell him to order another another bolt catch and try it or I would see about modding the one he had.

Best guess here, the bolt catch spring channel was not milled correctly/deep enough (or debris in the channel never cleaned out at the build), and between the spring full compressing and the detent limiting such, the two maxed out how far the catch could actually rise. Even odds says that if you pulled the catch, and just ran in a drill bit to clean up the bottom of the spring channel by hand, the problem would be solved. |

Are they all fixed stocks or collapsable?
I bought a new collapsable stock awhile back and couldn't get the bolt to lock back. Someone here suggested checking the spring and sure enough it had a rifle (fixed buttstock) spring in a carbine (collapsable buttstock) stock. The carbine springs are shorter by about 1 to 1/5 coils. |

i had the same problem... i was too inpatient to wait til i got a new catch, so i took off the existing catch and ground a bit off on the side that goes up against the spring with my dremmel tool.. re-installed and it works like a charm..
