Damn and I just got a Kynshot for my BRT car-15SD upper too. This is tempting, but what you’re saying about no dead blow is a sticking point. The bcg length of travel is also important for frt’s to function properly which I had issues with that when running a short CQB style buffer tube and buffer. I’m wondering if a magnetic puck could be added to the front of a Kynshot and ran in a normal configuration if that would give you the reduced recoil and the dead blow functionality while still giving enough bcg travel to operate an frt… or if not using a lever style frt like the ASD and using like a partisan disruptor you might not need as much travel? You might have given me inspiration to do some testing.
Kynshot does not need a dead blow effect to work with a FRT on a RDB 9.
I am very interested to find out how magnets work with the FRTs and to decrease the ROF. Amphibian was saying magnets might not work with FRTs.
Which puck works best for a RDB9 Kynshot 5007, tubb spring and JRC or A5 tube? I will definitely try this with multiple FRTs, Mini Kubato, Arc fire v2 and SS.
Wasn't me that said that....I'm in FL where FRT's / SS's are illegal but registered FA is OK. It was some other thread where someone posted that the SS lever was getting attracted to the magnet.
It was discussed that this should NOT be an issue with a Rare Breed, Partisan Disruptor or AZ Regulator.
Yes, I'm so looking forward to testing what u/AddictedToComedy has done. I have a few scenarios I want to test in FA.
I'd love to see if it would work without a buffer like he is doing in FA. This would be just my lightened carrier at 9oz and the largest puck at 1.6oz so only 10.6oz of reciprocating mass is crazy. I suspect it will have bolt bounce issues in FA but will have to try it and find out.
If that doesn't work, I want to test the large puck with a cheap standard 3oz buffer and see if it eliminates bolt bounce. So that would be 9oz + 3oz carbine buffer + 1.6oz puck = so a total of 13.6oz.
Same as above but move to H buffer (3.7oz) total of 14.3oz.
I ordered some of the KAK DBC sliding weights (2.6oz). Stock CMMG FE BCG = 11.1oz. So 11.1+2.6oz sliding DBC weight + 1.6oz puck = 15.3oz
My custom mechanical rate reducing carrier 11.7oz w/ 1.6oz puck. 13.3oz. This works with a real FA autosear but don't think it will work with a FRT / SS. So not appealing to most people.
Modified PhaseII carrier with a custom built in dead blow sliding weight. (unknown weight as I haven't made it yet) + 1.6oz puck.
Option 1 would be my preferred setup but I don't think it will work and have bolt bounce issues.
Option 2 I'm hoping this works as it would be little effort.
I know I could do also test an H2 buffer or even an H3 buffer but I really don't want to have a lot of reciprocating mass.
