now cycles low brass

Recommended Posts

500 rounds later and after some polishing work she is working great and spitting out federal 1145fps no problems.

Since shooting last time I did the extractor mod and removed metal from the bottom lip, removed all the sharp edges and polished,

I procededed to removing MORE metal from the carrier and bolt and re-polished both of them and also gave receiver rails a polish.

I then lubed the carrier and rails lightly with brake caliber grease applied from a Q-tip.

Any of that polishing could have done the trick, but I also swapped out the "nippled" CSS puck for the stock puck which I believe is what made the difference. Stock puck weighs about 17 grams more than CSS puck. This time around I cycled over 160 flawless low-brass shots 4 different brands (estate, Winchester, federal 1290& federal 1145 fps 7 1/2 shot). Last time shooting the federal 1145 wouldn't feed for shot on a maxed out auto plug and now I have 2 turns of adjustment left and it are it up just fine.

Before I had a 160 round flawless feed I only had about 3 failure to ejects and 1 failure to feed(the shell jammed up top where the extractor foot sits, I have slightly removed and rounded the material better since)


I'm stoked that I have been able to get her running good and had the time off work to get it done, hopefully she stays running this way.
