Trouble shooting a customers lower that would not run the KIKASS FRS.
1. Tested with lower that was sent in to us, with our upper, customer's carrier group. Confirmed it would not run in FRS.
2. Replaced customer's buffer with our H2 buffer. Ran perfectly.
3. Tested with H3 buffer and it also ran fine.
4. Took apart the buffer and discover it had only 2 steel weights, not 3. And buffer body is solid where the other weight should have been. Its also wider in the body and that drags on the recoil spring that could cause delay in timing.
These, often imported, buffer systems do not have the dead blow effect needed to prevent carrier bounce. It ran fine in semi auto but would not run in FRS. Not surprising the recoil difference with the H2 with 2 Tungsten and 1 steel weight was noticeably softer.
