those ARC mags look niiiiice! way easier than modding a pmag.
while we are on the subject of mags, iv been messing with mine trying to get rid of leaks. lithium grease is working great for me, got 2 mags up and running yesterday that would not hold gas before, but i noticed something. it seems like the ability of a mag to hold gas is closely related to the match between the mag body and the back plate. i would grease up the seal, install the backplate and get everything locked down- and the mag would leak, usually at the top or bottom. re-try with a different back plate, same seal and body, and get a perfect seal- no leaks at all. i should also note that all my mags have over-fill type valves on them, so no leaks is pretty impressive i think. to figure out if the back plate is a good match for a shell, put it on the back with no rubber seal in between. the top and bottom edges should sit really flush with the mag body, like right in there. most of the big leaks on my mags were coming from the top and/or bottom of the back plate so i think this is a key area for leakage.
as a side note, has anyone tried re-threading the female threads in the magazine? im talking about the ones that hold the back plate on. i stripped one while tightening the back plate screws
damn zinc
i recently received a replacement part #59 (knocker cover) from renegadecow on arnies. it is a home made knocker cover made from steel. its really nice and dropped in perfectly. it doesnt have the sharp internal corners that the stock part has (just a hole for the knocker nub to poke through) so i dont see it breaking any time soon. if anyone needs a new #59 i would highly recommend this part. only cost $15 shipped from the Philippines. i can post up pics if anyone is curious.
one last thing- ordering from airsoft buddy. has anyone done this recently? did you get your stuff in a decent amount of time? im always nervous when ordering from over-seas.
