I took my RRA 20" out to the range this morning. Every shot (minus a sqib) went bang without a problem. The issue I had was with the feeding About 3 mags into the 11 I shot, I started to have feeding problems. Every time I'd hit the bolt release, it would only halfway seat the round. I would be forced to hit the Forward Assist to get the bolt to close. After that, all rounds would feed and fire flawlessly till the next mag. I was using USGI's with Gen 2 Magpuls, USGI's with Greens, and HK 2nd gen mags. All of the mags had the same problem at the same level (no mag worked better than another). What could be causing this problem? It has not happened in the past on this level. Is there a certain area of the rifle I am not cleaning well? Where should I concentrate lubricant? I have CLP in a spray can, and Hoppes oil I can use drops with. The CLP always seems to soak things way too much. If you can post pictures or a link to pics on exactly where to put my lube and how much, I'd appreciate it. However, this could be completely unrelated. Thanks. |

You didn't say what kind of ammo you were using.................sometimes Wolf can deposit sticky junk into the chamber that can interfere with the bullet seating. CLP is the best solution................ just a couple of drops on the bolt and carrier can keep the carbon build up from slowing down the action. CLP breaks down carbon before it can build up on parts. Try to wipe the chamber with some CLP during the shooting session...........follow with a dry patch. JF. |

Ok, let me try to explain it more clearly. When I hit the bolt catch release, the bolt will come forward and grab a round. Instead of ramming into the chamber, it will push it half way out of the magazine. The mag won't release, but the bolt isn't stuck. If I hit the FA, or if I charge the handle again, it would seat the round all the way. I really don't know how to explain it any better. If you still don't follow, thanks anyway for your attention to the matter. |

Are you using the correct length buffer spring and correct buffer? Using an aftermarket stock or different stock than the original? Is the gas key aligned and not rubbing or catching on the gas tube? Check to see whether the key's tight and not wobbling around. Randall |
| Check the rounds that get stuck. Does the bullet itself have 2 real deep gouges on either side about a third of the way back? If it's a new rifle, your feedramps may need a quick deburring. I find it's either that or magazines that are the most common cause of the problem your describing, and you've eliminated one part of the equation.... |
This is an OEM RRA Standard A4. All I have added was the Hogue Grip and rails. And this one's a little embarrassing...which is the gas key? I can disassemble this thing blindfolded in seconds, but I've never learned what all the little parts are called. I am familiar with the receivers, carrier, bolt, firing pin, retainer pin, gas tube, but I don't know what the gas keys and gas rings are.
I don't think it is the feed ramps but I could be wrong. This is a relatively new rifle (6 months old) with about 1,500 rounds through it. When I first got the rifle I had this exact problem. It seemed to fix itself later on, but the problem has obviously returned. I'm stumped. I'll be taking it to the range again this weekend. I'll let you gusy know if the problems persist. |
Try downloading the mags a round or two. Might have a weak recoil spring as well. If the problem is exclusive to the first round from the mag after hitting the bolt release, it's probably one of those two. |

Well these mags aren't new. I have a bunch of 6 month old ones that do the same as my one month old, which do the same as my HK mags. I went again this past weekend with mags downloaded to 28 each. 2 of the 6 I brought had the problem. I am going to continue to use 28 and see if this was a fluke or if downloading helps. I again thank you all for the help. |
