The Bushmaster Regional Tech. Rep. came through Houston and we put 850 grain BMG metal down range with the Bushmaster/Cobb .50 caliber masterpiece. 30" floated barrel and 10 round mag.

It really isn't as clean looking as the Barrett, but the left hand bolt with the rollers is very smooth. I don't know which is better, they're just a little different. I know the Barrett gets more manageable once you shoot it for a while, you can shoot it offhand, but obviously not the preferred shooting position, just as a novelty for myself and some buddies. How'd the Bushmaster shoot?

Prior to Bushmaster's acquisition of Cobb Engineering, Cobb had invested many years and over $2 million of R&D into its .50 caliber systems. Bushmaster brought the Cobb platform up to Bushmaster standards and performed extensive field testing and fine tuning before bringing the Bushmaster/Cobb .50 cal to market. I fit a 42x NightForce/LaRue optic and GG&G heavy bipod on the system and the dozen or so 24" 600 yard hits felt stable and repeatable. The system is professional grade and I'm sure Bushmaster will have great success with this system.

Here's the but:

Ronnie Barrett and his team at Barrett Rifles have dedicated themselves since 1982 to providing our troops and law enforcement agencies with simple, very rugged bolt action and semi-automatic .50 caliber systems. Ronnie and his managers are constantly in the field listening to troops, LE agencies and civilian shooters and continue to improve their systems. Barrett has pioneered many areas of weapons, optics and ballistics technology and check out the BORS sighting system at www.barrettrifles.com. Technology similar to BORS has been in the field for some time, is now available to the public, and takes a lot of the guess work out of long shots.

I'll stay with the Barrett 95 bolt action system and would recommend the Model 82A1 to civilian shooters would want semi-automatic fire. Our military has thousands of Barrett M107 semi-automatic .50 cals in the field and they are putting a hurtin' on the BG's.

Hooyahh...

I've always heard great things about the 95, any idea which can seems to work the best on a .50? I know a little about the AWC and I believe John's Guns did one that was actually used on the Cobb I saw at SHOT 2 years ago.

I've seen a few .50 cal suppressors and am familiar with John's suppressor. John's cans are well made, easy to disassemble and clean, and purportedly reduce the Model 95's report by 70%.

Regarding recoil compensators, Barrett and JP Rifles are outstanding.

As far as muzzle brakes for smaller calibers, a friend of mine who is a Master Guns at Pendleton swears by the brake that Barry Dueck at Sure Fire does, it takes their can quickly and when you've got the can off of the gun there's virtually no muzzle rise. I may have to try that one next.
I need to pick up another .50 bolt gun (I've sold the ones I've had) so I can put a suppressor on one, it's very cool to hear the gun fired. Unfortunately, if you put a can on a SASR it voids the warranty.
I'll have to look into Johns Guns .50 can more.

The Surefire combination muzzle brake/suppressor is well engineered and well made. The quick disconnect docking system is stout and locks in very well. I've seen the 5.56 version and the largest caliber muzzle brake/suppressor system Surefire manufactures at this time is .338.

Surefire made a good move in bringing Barry Dueck on board and I look forward to their .50 caliber muzzle brake/suppressor system getting to the market. www.surefire.com

What's a running price on the BM model (for us cheapskate fools who wish for a Barrett)?

Professional grade .50 caliber bolt action systems start at about $3,000.00 and semi-automatic systems begin at about $8,000.00 plus hardware and electronics options.

Using today's technology, a complete Barrett M82A1 shooter/spotter 2,000 yard set-up with full Gen II NVD capability and shooter/spotter com links will cost about $25,000.00 to get started.

Other anti-asset rounds are being developed but the 950 grain .50 caliber HE/AP BMG round remains the most effective equipment buster on the planet, and pound for pound today's .50 cals are the most effective shoulder fired, hand portable convoy stoppers.

Using high speed DOD cameras, test rack mounted, running truck and passenger car engines have been filmed getting hit by 950 grain HE/AP rounds from different angles and distances. Post-detonation footage and photographs are most impressive and these rounds are indeed one-shot engine killers.

As to 50 BMG rifles, there is a garden variety out there. I will have a new Bushmaster (built on the Cobb design) in my hands shortly. I shoot competitively and regularly at 1000 yards and have had the pleasure over the years to shoot most every manufacturer fo the 50 BMG rifle. This includes all Barretts, McMillans, Cobbs, Spider Ferret 50, Armalite, Advanced LLS, the LAR Grizzley, EDM, Watson and a variety of custom bench rifles, to name a few. I have also owned and shot extensively the "ma duece" 50 BMG Browning machine gun which is a blast but the ammo is expensive for an afternoon. I currently shoot an Armalite single with a nightforce bench 22x42 and have placed rather well in the recent matches. I recently sold my McMillan tactical 5 shot repeater in lieu of the Bushmaster coming. I am anxious to shoot it and will let everyone know how it performs.

There are matches around the U.S. monthly and the world championship is in July in Raton, NM. You can get into this sport for couple thousand or spend as much as you like. A decent single shot with quality optics and accessories will put you in the $4000-4500 range or so. Just like any other sport, you can spend stupid. I also have and possess a wealth of info on 50 BMG rifles, suppliers and gurus that I will share with reasonable folks.

happy shooting at 1000 yards plus.
