So I picked up a .50 BMG action a little while back. It is a McBros Fisher action and I'm looking at getting the parts together to build the rifle. The first major part I guess would be the barrel. I've been doing some research and come up with a list of barrel makers who have 50 cal offerings. I'm sure there are more but these are what I've found so far.
all prices are for 36" or close to
1. Lothar Walther - button rifle
price $350 (CM??)
2. Lilja - button rifle
Lilja Precision Rifle Barrels - 50 Caliber Precision Barrels
price $495 - SS
3. Krieger - cut barrel
Calibers & Prices
Price $540 - SS
$410 - CM
4. Bartlein Barrels - cut barrel
Bartlein Barrels, Inc. - Barrel Pricing
price $540 - SS
$420 - CM
5. Pac-Nor - button rifle
PAC-NOR Barreling, Inc. - Price List
price $536 - SS
$466 - CM
Twist options 1-15
3 groove - Pac-Nor
6 groove - Lilja
7 groove - Bartlein, Lilja
8 groove - Pac-Nor, Lothar Walther
Polygonal - Pac-Nor
According to their site Krieger will accommodate most twist options.
I guess now I'm trying to figure out if there is any benefit with a particular groove design? Would any specific barrel manufacturer be a clear choice? Any experiences others might have with building a BMG rifle. This will be my first rifle done up from an action.
Also what are people using for muzzle brakes on BMG rifles? I'm leaning towards the Armalite AR50 or that style brake as I've read good things about it's recoil reducing benefits. I'm not worried about the noise or blast but do want a rifle that is fun to shoot.
