I bought one of theses recently and I have had problems right from the get go ...
1. The mag is very tight and hard to load rounds past 10. The loading process actually puts dents into the round under it because the spring is tight.
Is there a way to exercise the spring with wrecking rounds to loosen it up?
2. Without any mods to the feed lips, the mag feeds the rounds (when it can actually strip one off) into the extraction port. The left side of the feed channel had a huge burr in it. I took a file to this and rounded it off.
3. Once the mod was done, the bolt pushed the round into the bottom of the barrel causing it to jam and bending the bullet out of the brass. And when it does fire, I only get about 2-3 shots off before it jams the bullet up and ruining it.
Any ideas?
I dont think the thing you refer to as a "Huge burr" is a burr at all. you shouldnt have files it off! you did the same thing the guy who sold me his marauder did, and it wont barely function now. That bump is supposed to be there. I bought two more from Mystic Prescision (now waiting on another), and i left them alone. Im finding tha tif i use cheap bulk winchester lead bullets (no jacketing, or "plating if you will") they wont feed worth a damn! I can get one or two shots off then they stick, they wont load into the chamber, they get caught up on the bottom of the chamber, shaving/denting the lead nose of the bullet.
If i use jacketed, or pated bulk ammo, (Federal 525, or Winchester Dynapoint GT), they work ALOT better. I have even got the odd mag off without a jam/fte/ftl (failure to load).....
I'd REALLY like to see these come out with steel lips like the factory ruger, or BC mags though! and they should sell us just the upper portion of the mag, so we can easilly convert our mags to steel lip ones!
I have that one bad mag which the previous owner screwed up, and i can't get Pro-Mag to send me a replacement top piece for nothing. they said i would have to send in the whole magazine, but they wont ship to Canada anyways, so i'm just screwed. All they'd need to do is send the "lips" and i could pop em on... but no. What a bugger!
---Update.
I JUST got an RMA# from ProMag, but i have to have the replacement shipped to a parcel service i use in the US, so i will mail it out from the US to them next time i pick up stuff from said parcel service... ;-)
