| Have a fairly new DSA rifle, have had a few issues (sent back to factory, new bolt, etc) Anyway took out to the range today to adjust the gas system and still had several FTE/FTF I was using some surlplus nickel ammo that had some slight corrosion which might be the problem but I noticed the problem seemed to happen more with one mag than the other, only had two with me. Also noticed that the bolt seemed to cut a gouge in the next round in the magazine. Hope this all makes sense adn someone can offer some advice. |

Sounds like you need to put some more lube in the action, not grease but CLP or some other quality gun oil.
FAL's do not usually like grease and the original manuals even say not to use grease. Also it's common for a new DSA gun to need a couple hundred rounds shot through it to break in the action. The parkerizing is kinda rough and needs to be smoothed out with use. Also sounds like you should close the gas regulator a few more notches, you want the brass to be going about 10 to 12 feet to your 2 O'clock position. |

Interesting about the grease, when I got it back from DSA they had greased the bolt/action a fair amount. Thanks for the info. |
| 10-12 feet is a bit much. usually aim for 6-7 feet. The ammo is likely not the problem as I have shot plenty of the German surplus with some corrosion and didn't have any problems. I have had one or two bad mags but they would feed at least 19 rounds before jamming on the last. If it is taking a dent into the next round it is most likely your magazines or your magazines are sitting to low and its not catching it properly. |

Problem is when you set your gas to eject cases 6 to 7 feet if you shoot a long string of shots and your gas system parts heat up your cases start ejecting 1 to 2 feet or not at all and you have a FTE.
Seen it happen a lot at the GA. FAL match where there is a stage that requires at least 80 rds being fired in a timed event. About halfway through the run guns start jamming. Close the gas regulator two more clicks after you set it. |
I look at the bottom of the bolt to see if there are any sharp edges that cut the brass. There almost always are, but they get polished off during the break-in. I polish them off with a Cratex bit ahead of time, just because I hate chunks of brass in the action (never touch the face of the bolt that picks up the cartridge from the mag). Also, from looking at the posts here lately, it does indeed seem as if there are more bad mags out and about then there used to be.
