I've recently switched from a SIG 522 to a .22 BAR 15.
It appears to have done very little, and the previous owner told me that he had feeding problems. I tried it for the first time today, and it clearly can shoot, knocking spots off the accuracy of the SIG, but it did seem to have an issue where the bolt kept stopping short of battery with the round tight in the chamber. To be specific, it appeared to have fed properly, up the feed ramp, but was sticking when almost in the home position. The chamber and barrel were checked and cleaned, but looked OK as far as I could see. I tried many different types of ammo, with similar results. Any other owners care to offer some advice please? |

I've got a BAR in .22 and never had a issue that was related to the rifle (had a problem with crap ammo and another when I failed to tighten the castile nut)
If I did experience a problem with it and giving it a clean didn't sort it, I would speak to the person who built it directly and ask his advice... |

At least with out taking the barrel off the upper, prob better to de barrel and center in a lathe and slowly polish that way with polishing compound but not everyone has a lathe. |

Before messing with polishing chambers, wouldn't it be better to see if there is any damage from dry firing, or checking the extractor claw for example? Better still, suggest that Ballistol contact Mark directly and get the gun looked at by the guy that built it. Taking a drill and brush to a chamber is not the first place to start.

When all the facts indicate to needing to polish the chamber and even cmmg advice is to do the same then maybe its a good start, check the firing pin but I doubt it is damaged. The only way to solve this is by a process of elimination, but what ever we will fin out eventually what was the problem, well not if it was a unicorn and certain interesting facts come to light but don't...... Or he might decide to flute his chamber with a dremel, would be a new one.

No no your quite right don't clean it and eliminate that as a potential problem, assume mechanical failure and contact the builder

As for firing pin damage, depends on the trigger you have installed,
And anyone with a heavy hitting trigger in a bar .22 will agree. Mine has eaten at least 3 firing pins in the last 12 months Take the bolt out and look at it, the flat of the firing pin should be vertical and If you push the pin from the rear it should protrude and return by the same amount. When they go, they will still fire fairly normally |

Thanks for the information lads, I'll drop Mark a line.
To answer a couple of the points raised:- Chamber/barrel look clean to me, I have no intention of performing any surgery to it. I did try CCI Minimag, which seemed about the best of the 10 or so brands tried. Some rounds would barely enter the chamber, even by hand, and when time permits, i'll meaure them. |

Jeepers, I never thought suggesting a little cleaning/polishing would be so controversial.
I was only recalling what I had read on this thread a while ago, Link I just was too sleepy to search out the thread last night. The information in the thread helped my (and many others who replied to the thread) .22 run smoother. Personally, I like to have a go at sorting things out myself, provided the processes aren't too complex and the risk of causing damage seems manageable. |

Its best to let Mark check it out, as I said there are many factors that could be causing the problem and it may be that its nothing to do with the chamber at all and more about the feed lips on the magazine that could be damaged or worn, thus delivering rounds at the wrong angle. If the round is chambering but getting stuck half way and is in tight then more than likely the bullet has become deformed at some point and is causing the jam. This would usually happen when the chamber mouth is miss formed (from dry firing), damaged or not radius'd properly, the bullet strikes the edge of the chamber mouth as it is loaded and the soft lead gets knocked back causing a dint & bulge, as the round continues into the chamber that bulge is forced in and jams the round up. Even if the mouth of the chamber is smooth this can still happen when rounds are not delivered properly from the magazine. As the round leaves the feed lips it must spring up at the rear and slide into the firing recess on the bolt face, if for some reason this is not happening or the angle is slightly out then the bullet can again strike the mouth at the wrong angle get dinted and cause a jam. There are plenty more things to check also but its impossible to tell without looking at the gun. |

Just because he said it was cleaned, doesn't mean it was clean. I often tell the Mrs. that I have cleaned the house but for some reason, it never counts as being clean

I exchanged e-mails with Mark last week, and to be fair I couldn't really have received more help.
His response was prompt and detailed but listed some of the more basic things I could check myself, with the offer to have a look himself if I couldn't resolve. I'd planned to try it again at the weekend but the range was closed due to a local airshow. Latest plan is to try Tue/Wed. |
