    I doubt this will pertain to many people but just in case. I got a Alexander arms 50 beowulf upper recently. The upper comes with one magazine. Replacement mags are hard to find, cost in the $26-30 range. And many people complain about the tilting follower that likes to stick.

    Turns out the magazines are just metal AR magazines with slight modifications.

    the only difference is the front lip of the magazine has been ground down so that the head of bullet does not catch when chambering.

    Here is the alexander arms one on the top and my modified one on the bottom

    The red line here indicates where I had to modify

    Finally, replaced the follower with a magpul self-leveling follower so it does not tilt and get bound up when putting in rounds

    So a $30 mag can be made with a <$7 metal AR mag like one of these

    with a non-tilting follower for about $1.80 each

    I did try a PMAG but the polymer is just not strong enough to hold the rounds in place and it starts to bow out.

    Well done!! I make mags for my .308 Galil by modifying M-1A/14 mags with a Dremel and spot welding hand filed/ground front/rear lugs to them, because factory mags are as scarce as hen's teeth, and SPENDY.

    I can't say I'm a fan of plastic mags, and only use USGI/STANAG mags in my AR's, including my 6.8SPC (with a 6.8 follower). I've NEVER had any issues with one in 30-yrs since I first laid hands on an M16A1 in basic training.

    I've had a macked-up AK47 mag that was corroded just enough inside at the middle that you could only put 7 rounds in it before it goobered up.

    How do you like the beowulf? I have a friend who has one who has tried and tried to talk me into buying it. He wants like a grand though (it does come with a few mags and some ammo)

    Seems like it would be fun, but I dont know that I would shoot it enough to justify having it.

    Just got the upper a few days ago and ammo and the lower yesterday. So my only experience is loading mags so far. at $1.50 a round I wont be shooting it too much, but I wanted a 50 caliber something and this was the least expensive way I figured out how to do it.

    Hey Doc, $1.50 is half the cost of some .50BMG rounds I've been seeing on sale lately.... You should get a .50BMG single-shot bolt-action upper for your AR too. ;)

    Shoot, $4 a round for the .50 BMG is cheap. Try buying ammo for your 20mm Anzio :D

    I'd love a Tactilite upper but a bit out of my price range now

    Yeah I have looked at the Tactilite, I think as far as drop on .50 BMG uppers its the one to have. I think if I had a good place to shoot it I could come up with the dough but right now it seems pointless to tie the money up in one simply because I have no good place to play. If you dont have 1000 yards at least its not really .50 worthy

    Are those AR15 or AR10 lower compatible?

    on the other end of the price spectrum, apparently this is a thing:
    26 round mag.

    I dont even know how you would reach around it to hold the gun. Perhaps you just hold it to your chest and hug it.

    Went out shooting today the last few rounds in the mag are snagging on the lip of the brass. Rounded it out with the dremel and it should be fine now. even did this with the factory mag.

    Is it impossible then to convert PMAGs with windows, or PMAG40s to .50 Beowulf mags? Thanks for sharing.
