Has anybody retro fitted a magazine on to an AR50 or is it not possible.

It was done before, I can't remember the name of the company that was doing it but as far as I know no one at this time is doing it.

It's a great idea but alot of factors play into cutting another hole in the receiver on the AR-50, first is safety and second would be the additional flex/torque on the receiver. The safety part can be overcome but the flexing/torquing of the receiver can't and that will affect the accuracy of the rifle.

I would have to say if you a magazine fed firearm go buy one, already designed for it. Not that it can't be done, just not sure if it is worth it.

If a Magazine mechanism could be added to an AR50 in a manner that wouldn't comprise the structuralism of the firearm for less then $500, I would say that is a great deal. AR50 is half the price of the Barrett and the bushmaster, so a $500 upgrade would not seem so unfeasible.

Plus, I already have an AR50. It is a great shooter and looks like a million bucks. I could see spending $500 to add a magazine to it.

That's the point we are making you can't add a magazine with out adversely effecting the rifle as far as accuracy, and structural strength goes, flex and torque. There maybe a way to do but in will probably cost as much as or more than, just upgrading to something else. If was a $500 option to do it you would see a lot more of them and you don't see them.

+1. As said above, it has been done. But it's an accuracy killer due to flex from what I remember.

No need for a mag. Limits your OAL anyway. If you need a magfed for cheap, get a Tactilite.

If you need a magfed for mucho dinero, get an EDM or a McBros.

Ya, but lets remember one thing here David. From all of the post that I have read here on this AR-50 rifle. Is that the throat is so long that you can not load a round so that it even comes close to touching the lands. So, are we really worried about the seating depth / OAL on a AR-50? But in overall, I agree with all who have pointed out the weakening of the action and the reduction of accuracy and most importantly the chance that it could become a safety factor some years down the road when the frame fails due to repeated stress.

I'm not going to make a jugement on how a mag wouls effect anything untill I see one that has been done. This has came up a few times and not one pic of a AR50 done has been shown much less a review of how one shot before and after a mod like this

My thoughts exactly.

Look how many 50 bmg uppers there are that have magazines. Those receivers are no way as stout as the AR-50 and they have magazine and mag well cut outs.

The AR-50 has the tri-lug bolt head that locks to the front part of the receiver past any potential mag well cut out.

So, are you saying that you think all of the recoil, whip lashing and vibrations end where the bolts lugs engage the front of the receiver or the barrel extension meet? Interesting! very interesting indeed. There for anything behind this location has nothing to do with the accuracy of the rifle. Might of fact I could have two toothpicks between this location and your stock and it would have nothing to do with how the muzzle would react to a 1/10 ounce bullet is forced out of the barrel doing at least 2400 fps, and being spun up to about 115K RPM. Na, makes no difference to what is behind the locking lugs.

Well that might be what you think. But I will stick with a good strong receiver behind the locking lugs to be a requirement to a good accurate rifle.

Oh, and for all of them other rifles with the magazines. I wonder how many of them are being used in comp. shooting out to 1K yrds? Anyone know of one that is winning at those shoots? Wonder why no one will answer in an affirmative to this question? Thats cuse none of those magazine fed guns have the accuracy of a non-mag fed rifle. You weaken the action and the gun whip lashes thus your now have a MOA greater than 1 with match rounds.

COBB was the company that was doing the magazine conversions to AR-50's. They sold out to Bushy so they're no longer done.

My google-foo has failed to reveal a picture anywhere of this setup but I did find one old phantom link to a company that used to sell the mags.
