Just fired it today with some friends.
Another technically innovative design from Keltec.
Lightweight in its' original form, versatile.
No problems with FTF, FTE.
Worked with a variety of magazines and ammos.
Mounting an appropriate sight it could be brought under 1 moa if needed.
Easy to strip, assemble and figure out.
Installing the bolt carrier and piston will take a bit more practice in manipulation and the sights we used for irons were lowered to the lowest limit to zero.
Otherwise a very positive experience with a new rifle.
I actually liked the original stock and forearm/bipod, more than the railed forearm and collapsing stock version.
