I'm having problems with magazines feeding. I have one mag that seems to work 80% of the time. The mags seat and lock in place, however they do tend to move forward and back quite a bit. Any suggestions or tips would be of great help.
This is what i have Rock River 9mm complete upper. Cmmg complete lower CProducts mag block CProducts Magazine Colt 9mm Buffer and spring The ones that don't seem to work actually press the bullet tip back into the shell casing. |

try putting some layers of tape on a couple sides to take out the slop. its a cheap/easy way to see if it is a mag issue.
when i got my OA K9, my LGS said to make sure the mags didnt have alot of slop. that was a good majority of the problems with those pistol ARs. if it is a mag problem, then try to adjust your MWB. |

Dump the CProducts mag block + mags.
Get RRA mag block and Metalform mags. Both available at Spikes Tactical. Metalform made the original Colts 9mm SMG mags. 800-618-3318 part # 9-SMG-32-S $39.30ea You can get the CProducts mags to run with the RRA block by lowering it .015-.020" in the well. Get out your checkbook, just do it, have fun with something that runs 100% and never look back. |

If you have c-product mags already, keep them and try rra mag block. It gives you the ability to adjust and lock in place. Once set, (mine) hasn't moved and 100% reliable with c-prod mags. Shot with 115g,124g,147g with different bullet profiles and haven't had a failure (only about 300 rounds so far). I have a CMMG bolt so your results may vary.

I agree with only half of this statement-their block is apparently pretty crappy, but their mags are solid (though different from Colt/Metalform mags).Dump the CProducts mag block + mags. Quoted:
This works out to lowering the block to where the mag catch retains it and then re-tightening the setscrew. VERY easy and amazingly effective.

Follow the advise in this reply and you will have a gun that works as it should, without lowering magblocks, modifying mags etc. |

I agree with GHPorter, I lowered my RRA block very slightly, tightened the magblock hand I have fired over 2500 rds with my CProducts mags without a single hiccup. To me, lowering the block is no big deal. I have over a dozen CProducts mags and 6 Pro Mags and all work fine. The Pro Mags work OK, but the bulge when fully loaded and require a good whack to fully seat. With CProducts mags I can buy 2 for each MetalForm mag I buy. If I had to keep adjusting the mag block, I would have ditched the CP mags, but it amounted to loosening the set screw, lowering the block slightly and re-tightening the set screw and everything worked. I am an engineer by trade and I dont mind tinkering with guns to get them to work properly.
