I really need to check that out. Sounds like a bargain.
The 7.62x25 round has a muzzle velocity of 1525 ft/s. and a muzzle energy of 439 Ft/lbs.
It uses a roller lock mechanism similar to an H&K.
I love mine it's awesome, and the flying brass will kill at 25 yds.
Note , the standard round is on the right,
the saboted round on the left is much faster.
