I'm hoping to have everything up and running and shooting by then. I have 1 5rd mag coming with my Bushmaster upper. The magazine threads are making my head spin. If I could find a place to try a Bartz mag I would like to pick one up. The place where I bought my order, Walsh Gun and Tackle, has 6rd metal mags on their website as well, I'm sure these work fine also.
Look forward to sharing info about the 450BM.
The mags don't have to be so daunting to get to run reliably. I suspect a lot of the lip tweaking, which is the real juju part, is caused by the way overkill spring force in the mags. You'd think they were lifting 50 BMG rounds as powerful as they are. I cut mine back to where there is only a few ounces of lift remaining when that last round is in place. That's all you need, plain and simple. I don't long term store my mags loaded and have yet to have a spring go soft on me. I usually advise folks with stock magazines to polish the underside of the lips, where the shells slide across them as they're often phosphated or painted, or both. Do those two things and truth be told, most stock mags work pretty well. There may be a little lip tweaking still to be done, but like the table with one short leg, once you start messing with them, your in for the duration of the war. The operative word there is not to worry about crossing that bridge until you get to it. Remember the "Internet Factor". All the owners without mag issues have no need to come here for help. So when you read these threads, it would seem like everyone posting here has problems with their mags. Not many folks stop by to carry on about how worry free their mags are. There's always something better to do with their time. Relax and savor the anticipation of the fun you'll have.
Just know that we're always here to help you if you get stuck on something. I don't know how many ARs you have already, so don't take this advice the wrong way. Don't wait until the last minute to break your rig in. They run tight, sharp and stiff when they first get commissioned. Takes a while for operation to smooth out, unless you do a "melt off" (not to be confused with a destructive meltdown) and polish of all mating, gliding surfaces. Otherwise, run them wet and clean out the slurry after every range trip for a while. March is just around the corner...
