I use the 10 round 5.56 Lancer mags. I simply grind the original "hump" off the floor plate, grind out the U shape at the top front, cut 2 coils off the bottom of the spring, and cut down the plastic floor plate stopper and some of the tab that hangs down from under the floor plate. Easily holds 5 rounds. I also use 10 round P Mags. Those take a little more work (heating the feed lips and bending them inward a bit, grinding out the inside rib that runs up and down the front...) and also hold 5 450bm. I also use the 30 round Hexmags. I have to cut two thin wedges out of them to make them more straight instead of curved, and epoxy them back together. Those hold and feed 13 rounds of 450 bm.

I also use a standard 5.56 mag for the 450 bushmaster. Works fine. I only load 5 rounds, but that's all the 450 mags hold.

I really like all of your videos, Buffalo.

Bear creek is underrated. I got the .45O bushmaster, .50 Beowulf, 300 blackout, and a 7.62x39 all have run almost flawlessly with a minimal of 50 rounds or more through the barrel. Had a few feeding issues with my .450 but put a heavier feeder spring in and modified the mag and works great. That made my Beowulf shoot great brand new out of the box. It’s preferred if you clean the rifle out of the box which I usually do but didn’t with the .50 beo and it still shot great. You have doubts about bear creek budget uppers. At least give them a try if it’s a dud or manufacture fault they back it up with a lifetime warranty. I don’t know about you but I rather put some of my designated money into the ammo and optics.

450BM guy here...the critical factor for reliable feeding in these cartridges (esp. 450BM) is to adjust the mag feed lips so that the nose of the top bullet is sitting just ever so slightly "nose up" in the mag, when viewed from the side. The half-moon cutout at the front is usually needed, also.

Hexmag makes a great mag for those rounds, I can personally speak for it running the 300 blkout with no problems. Thanks , it's nice to have options

Got all the parts of a 450 ar on order, lots of help on KZread for this. I'm a builder so I'm not afraid of using my dremmel, so far I've found i need to clearance the ejection port and magazine, not much else. But my question is I've seen some videos and read a couple articles where people are having cycling issues, possibly short stroking. Do you use any special setup in your buffer? I have standard carbine buffer & spring on order for a 20 inch barrel, i just don't know if i should change the buffer or spring to a heavier setup or is that what's causing people's short stroke issues.

Amend 2 magazines work great. Just grind down the follower flat and the front feed area and they work awesome. Don't bother with the Pmags unless your using very short rounds otherwise the inside front groove will bind on the bullet tip.

bigboremag.com sells conversion kits for Gi Mil-spec mags and Polymer Hex mags, They work great too ! and you probably already have the magazines so for under $10.00 you have a big bore mag that works!

With your Dremel job did you just outline the brass or go a little beyond?

Why did you make a cutout? Didn’t yours come out with a cutout? Mine did and the one on there website does AND CAN you use these mags without the upgraded stack followers, just stock with the 450

Thanks for the info Buffalo. I am waiting on my 12.7 x 42 upper from BCA. Been watching all the videos about magazines. Yours are straight forward and clear. Where do you get your 12.7 x 42 rounds? Do you reload?

@buffalosoutdoors

I don't reload at this time but I am investing in dies soon. I like the Underwood Ammo 350 grain XTP loads and also their 380 grain hard cast for when I want to punch deep and don't care about expansion. Both loads shoot well in this upper. I get them where ever I find them on sale. I think that last order of ammo came from Midway USA.

Okay so I just got my Bear Creek Arsenal 450 all together and brought it out today to shoot it. It appears that it is short stroking a large majority of the time. The bolt usually doesn't come back to lock back and often times it won't chamber the next round. Not every time just a lot of the time. I've got a Spike's Tactical T2 buffer which is a 4 oz buffer. I'm wondering what you use for a buffer is it a standard 3 oz? Trying to figure out if going with a lighter buffer will help with this problem. It's totally worth dealing with a tad bit more recoil in exchange for a rifle that reliably Cycles if that is what will fix it. Thanks in advance for any help. Yours just seems to function just great so I thought maybe you could give a pointer or two on what you used for a buffer.
