X-PRT90 Short - :O

DESCRIPTION

I was asked not to show any internals. Installation was straightforward. The jig keeps everything in place, and whatever you do, don't push the rear pin all the way out because the spring is not fun to put back in. The FRT component installs on the rear pin. FRT works just like the P90 FA trigger. IF you light press you get semi auto and a reset, you need to press PAST that to get FRT to go.

The only issue I experienced is my original breach block/bolt/carrier has a rough spot, and was somewhat causing it to stick in the rear. I swapped to a newer one and everything worked as it should..
