Got two of these from Sixmm. One went into a ASG M15 URX-SBR, the other into Specna Flex M4. Simple fit with no modifications required. Easy reroute of power cable to rear (channel part of gearbox) into PDW stock, Specna required a little extension to get to end of buffer tube. 1.14J on 90 PSI on 6.02 x 230mm barrel. 16 rps. Excellent, affordable, super quiet and responsive trigger.
The part is lightweight well made and comes with 2 buffers a good product for speed or for winter use
Everything went together fantastically, no problems what so ever and the mounting system from my ris 2 locks up the ris 3 perfectly.
Fit and finish were perfect, no blems or anything, I'm currently trying to purchase the 9.5 inch ris 3 to build a mk18 ris 3, I'll definitely share once everything is together but right now get a look at the 12.5 ris 3. I Hope it does not disappoint.
