Ok, here is my question. I have Ar15. When I place the magazine in the lower, and pull back the handle, my understanding is that the bolt should be held in place, somehow..(the magazine is empty). Now, what should hold back the bolt?? Does the bolt get held back by this device that has a thumb like external handle on it(from the outside)? If so, My bolt can barely be held back. It just slips off this flat device that looks like it should come up from underneath it and rise up about 5 mm to hold bolt. Mine seems to only come up about 1mm and if you shake the gun, it will drop the bolt. What is wrong??? |

That "flat device" is the bolt hold-open. Remove your upper so you can see, and then put an empty mag into the lower. You'll notice that the follower of the magazine pushes the bolt hold-open into the up position, which is how it locks back on an empty mag. If this isn't happening, then your mag is the most likely culprit. Either the follower is binding (if so, install the anti-tilt Green Followers) or the spring is worn. You can try stretching the spring, but if the spring is the problem, you're better of replacing it. Bushmaster has kits. You can also try putting some oil on the bolt hold-open pin, or check to see if it's rubbing on something that would prevent it from moving up and down smoothly. Anyway, why is this in the Legal forum? [:)] -Troy |

Sorry about this being in Legal column. I forgot where I was...Do you want me to move it? Also, I did what you suggested, however, the problem is still that this hold-open devise does not seem to come up far enough to hold the bolt. Could this be by design for this receiver. I can not remember, if it ever held the bolt open. Were some receivers made to not hold the bolt open on an empty magazine? |
| Pull the takedown pin, and first check and see if you have good movement in the bolt hold open lever if you move it manually. If you cant move the lever very much by hand then you probably have some kind of blockage in the pocket that holds the return spring for that lever. If you have a good set of punches and have an idea of what your doing then you can remove the pin holding the lever in, and see whats up with the spring and the spring pocket. Just be careful when removing the pin, its easy to put a nasty scratch on the reciever. If you don't want to do it yourself it's probably not a real expensive fix for a good gunsmith. |
