Anybody here got one,which model? How do you like it? Where could I look to read some more info on them. Is there a forum like this one for them?  Any thing else you can tell me would be great.
Thanks

I can't say that I own one, but one of my coworkers does, it's an Armalite AR50. Having fired it, I gotta say that for a .50 BMG it's kick is really wimpy. Accuracy is good once the sites/scope are sighted in. It's heavy, very heavy. Ammnition is ~$4 per round (this may vary depending where you live).

I have the AR-50.  Love it.  With match loaded ammo it will hold sub 2" 5-shot groups at 500 yards.  Recoil is about like a lightweight 25-06/270.  Also for a bit more info, check out FCSA and Armalite.

check out the www.biggerhammer.net forums and you'll get all the answers you want...

Spooky

I have an AR-50.  Using a nightforce scope and talon ball (cheap $1-1.5/round) it shoots 0.5 moa out to 700 yards.  Recoil is very light.  It is heavy.  The trigger is heavier than I prefer for a this type of shooting (4-4.5#), but due to the design, you cant get much lighter safely.  At least I cant - some claim too, but having the firing pin follow forward when I closed the bolt was enough to scare the shit out of me and I went back to the stock trigger.  Other than that I have ZERO complaints and Im very impressed with the rifle - I made me enjoy shooting long range again.

There is a 50 cal forum in the Armory.
