Range review! The rifle is a blast to shoot. Put 300 rounds through it with no problems. Muzzle blast is not terrible, but it gets your attention.

See my other post about muzzle brake options.
I was able to get sighted in at 75 yards quite easily, and was able to get reliable hits while standing at 125 and 200 yards. I'll say it again, this rifle is just handy. It's very controllable and compact and would make a perfect bush gun if our laws allowed it.
One thing to note is that the FAB defense hand-guard really vented a lot of heat! After a few rapid fire stings you noticed it! I also officially hate the folding stock. For whatever reason it bashed my cheek every time I used it. I don't have this problem with the "'wood" stock. I'm going to try doing a paracord wrap and see if that helps, otherwise it's gone.
Now to the interesting stuff. I chrony'd my rifle with surplus Czech ammo against my buddies Non-restricted 858. I fired ten rounds through each rifle. I was very happy with the results!
858 Results: 19inch 7.62x39
AVG Velocity: = 2294fps +/- 21fps
DLASK Conversion results: 12inch 7.62x39
Average Velocity: 2119fps+/- 29fps
So we lose roughly 175 fps with a 7 inch reduction in barrel length! IMO this is very acceptable velocity loss for such an increase in portability and compactness. I was also impressed with the consistency of this ammo. Inexpensive surplus it may be, but it's ain't cheap.
