BTW the basic belt fed conversion from Valkyrie Armament, LLC is $3,300. You send them the gun, they modify it, add the belt feed mechanism, test it and send it back. The links are $35.00 per 100 links. Currently, they are modifying the links one at a time. That is were the high price of the links comes in. They are working on automating the process some.
If I owned a off brand (non Colt M16) I'd have no hesitation in having it modified. Someone originally milled, drilled and ground on it to convert it from a semi auto in the first place. Most have been modified because the semi auto lowers were out of spec before they were converted. I'm sure Valkyrie would send you back the pieces he cuts out. And M60joe could weld the lower back up so you could never tell that the modification was ever done. If you used a standard upper on the modified lower you'd be able to see the mag through the hole. That would not effect function of the lower, just cosmetics. I have no plans to take my full auto stuff into battle and roll around in the dirt.
Like "amphibian", I bought a sear so I could have more options. Personally, I think this idea is cool as hell. A belt fed host for around $4,500. How cool is that? Yes the links are pricey. I'm guessing the current market value of a Shrike for someone that hasn't had $1,000 sitting with Ares for 8 or 9 years is around $7,500. At around a $3,000 price difference, I can buy almost 9,000 links. If I loose 10% per belt, it would take me a lifetime to go through all those links. And I don't need to buy 9,000 links upfront. At $200 per thousand for Wolf, how many thousand rounds do you want to shoot in an afternoon?
My brother "Doctor Evil" has a Shrike. It is a great upper and very versatile. It runs like a top. My brother bought a couple of replacement barrels from Ares at $750 each. I'm having an old MGI upper modified for use with the feed mech. I can buy stripped fluted heavy barrels from Bushmaster for $230 + $175 for the piston kit without the hand guards or carrier. So basically 1/2 the cost of Ares barrels. I'm also having one of my water cooled uppers modified for use with the Valkyrie system. I can't easily do that with a Shrike.
Is this for everyone? Absolutely not. This is like a Beta C mag X 10. You can make the belt whatever length you want, but $3,300 is a lot of money, just for a really BIG mag. But a guy could go out and buy a LL and have one of these conversions done to a semi auto piston AR for less than $10,000 and have a belt fed machinegun. Please name for me any belt fed gun that has a market value of $10,000? Better yet, name for me a .223/5.56X45 belt fed gun you can fire from the shoulder for $10,000? YMMV.

P.S. I'll be sure and have a range report when I get the guns back and try them.
