Kel-Tec RFB with the OSS Suppressor

Shooting the Kel-Tec RFB, suppressed with the OSS Suppressor for the first time so I ran over 140+ rounds through it to make sure it was functioning properly. I originally ran this with the piston made for a suppressed RFB’s but I wasn’t having good results & I almost had the gas completely closed to get the rifle to run properly. I think because the OSS Can doesn’t produce much back pressure so this piston wasn’t working properly. I then put the regular piston in and found the rifle functions but under any gas setting on the piston. Hell I’ll take that. 😂 I just set it on 34+ & left it there I could've left the setting basically on 37+ which is the last position on my piston and it would work fine having most of the gas exit the piston. The rifle function great. Sorry this video is so long, but I wanted to really document the functionality of this rifle suppressed, plus there’s not much film out there on this spectacular Bullpup Rifle. I was shooting PMC Bronze 147 Grain FMJ-BT 2780 FPS. One issue I did come across is with the trigger, after firing over 100 rounds the rifle heated up tremendously and I notice the trigger at times became mussy and unpredictable at the break, you can see this on the video toward the end. I believe due to the fact the trigger is a plastic part, the heat can effect the trigger's performance. Hopefully some after market company will make a metal trigger for this wonderful weapon.
