The Desert Tactical Arms SRS Covert Rifle was definitely one of the niftiest guns at SHOT Show. With a short 16″ barrel, chambered in 308 Win, .300 Win or .338 Lapua Magnum, this gun has an overall length of just 26″. It is tiny but powerful package.
My only concern would be firing a .338 Lapua Magnum with a muzzle brake so close to my hears. The blast must be ear shattering.
I heard some interesting news about Desert Tactical Arms at the show. Apparently they have sold sniper rifles to Georgia (the country).
UPDATE: I found a note I took when I was at the booth. DTA has been using .338 LM loads with a 300 grain bullets, being pushed at 2250 ft/sec and 250 grain bullets at 2500 ft/sec. That is slightly slower than a .308 Win., but with a much heavier bullet. Not bad for a 16″ barrel.
