[wild_wild_wes]

Anyone have any more info about this?

And oh my gawd, look at the prices!



ABOARD USS ESSEX – Cpl. Trisan Wimmer, a scout sniper with Weapons Company, Battalion Landing Team 2nd Battalion, 1st Marine Regiment, the ground combat element of the 31st Marine Expeditionary Unit, engages a floating target with an XM-3 sniper rifle, June 2.

Iron Brigade Armory, under contract to the Defense Advanced Research Projects Agency [DARPA], developed and built the XM-3 to incorporate the best available technology into a sniper weapon system that addresses current operational concerns on size, weight, target detection, sound suppression, accuracy, range, day/night operations and the use of titanium. The XM-3 has established the baseline from which DARPA will identify investment areas where new technologies are needed to provide snipers and riflemen the greatest possible advantage on tomorrow's battlefield.

VERY interesting....


no DBM, surefire can, approx 18 inch barrel......

[Snake]

meh, I can have George Gardner at GA Precision do this for almost 1/3 of that price.

[blackheart3a]

Again...very interesting...and Mike at Tac Ops can do the same thing as well. The UNS is pretty spendy at about 9 grand a piece for LE/Mil purchase. Our agency just bought 2. That looks alot like range 116 or 117 on Camp Pen. They must be in the testing phase???? Anybody have more intel?

[nationwide]

Yeah, I just got wood.

I understand the short 18.5" barrel because of the can, but aren't they going to be loosing a lot of velocity? When will a .308 fired out of an 18" barrel go subsonic?

And the stock: a McMillan A-6, which means no aluminum chassis. Isn't that a great leap backward?

[Derek_Connor]

lack of aluminum chassic indicates the need for glass bedding doesn't it?

18.5 barrel, and they are claiming effective range of 1k yards with suppressor...

It will be interesting to see over time how often these have to go back to the armorer...but we'll never know

And the stock: a McMillan A-6, which means no aluminum chassis. Isn't that a great leap backward?

Not at all. Most modern sniper rifles are bedded with Devcon titanium and/or Marinetex.
Even rifles with the Al chassis stocks benefit from a skim bedding with either of the above substances.
Straight "glass" bedding isn't used for these types of weapons.
McMillan stocks are unbelievably tough!

BARREL LENGTH AND THE PRECISION RIFLE, Why shorter barrels may often be better, by Eugene Nielsen

During the development of the Tango 51, Tac Ops took a standard 26-inch barrel and cut it down to 18 inches in one-inch increments. Between 10 to 20 rounds were fired at each invrement. They found that a 20-inch barrel provides for a complete propellant burn and no velocity loss when using Federal Match 168-grain BTHP, a cartridge that has become something of a law enforcement standard. Going to an 18-inch barrel only resulted in a loss of 32 feet per second (fps).

VERY interesting article, f.2! Thanks!
