I am thrilled with my Kel-Tech SU16. Took it to the range today. What a delight to shoot! It is pretty accurate with the iron sights and they adjust well. When I took my time zeroing...on the bench...at 25 yards I got a night little cloverleaf of three shots. Off hand at 60 yards I shot some nice groups. I have a 2.5 power scope I am considering as a candidate for this light rifle. I did not use the built in bi-pod today. I will save that later...I have heard that using the handguard/bi-pod does change the POI. The recoil on this rifle is sweet. I am thinking - great home defense, SHTF, and truck gun all rolled into one!
