I received this Sks in a trade and wasn't told it was trimmed and crowned at 14". Had a "pipe" for a "flash hider". Anyhow. I welded a muzzlebrake on that brought it to legal length. I've had some feed issues with but seems to be pretty accurate. The only magazines I've tried have been Tapco 20rd mags. I tried stretching the springs in them to see if that helps. Helps some but every now and then experiencing feed problems. Has anyone ever done a 8 o'clock o 4 o'clock "feed ramp" and polishing. Looking for opinions on doing it. Not the opinions of "get and Ak". This is a project toy and I have had fun with it but a fella is aching to buy it. I don't like to get rid of something until it's 100% up to par.....any help would be appreciated. Thanks.
