JBeck Posted May 20, 2016 Share Posted May 20, 2016 HI guys, My Krytac recently chrono'd at 310fps using 0.20g BB's, just wondered if anyone out there has upgraded anything internally to make it more powerful and accurate. I am under the understanding that the spring is super easy to replace. Also what weight BB's are you Krytac CRB owners using? My site is outdoors and the limit is 350fps like most other UK sites. Cheers Joe Link to comment Share on other sites More sharing options...
Guest PT247 Posted May 20, 2016 Share Posted May 20, 2016 Just do a spring change and that is all it needs. I run mine with 0.3g BBs but that is just about as heavy as the hop will lift properly. The hop is darn near perfect so don't mess with it or the bucking. I tried a Prometheus inner barrel but got no improvement over the standard so put the original one back in and it shoots fantastically. Link to comment Share on other sites More sharing options...
JBeck Posted May 20, 2016 Author Share Posted May 20, 2016 Brilliant what type of spring would you recommend? Ah right I might try 0.25g BBs next time and order some 0.3g's. thanks for you reply Link to comment Share on other sites More sharing options...
Guest PT247 Posted May 20, 2016 Share Posted May 20, 2016 I couldn't say for the CRB as my SPR has 410fps and is locked to semi, my PDW is the 350fps gun but due to it's shorter barrel would need a stronger spring than your CRB. Try an M100 and see what it chronos at, if still low try an M110. My SPR has an M125 Link to comment Share on other sites More sharing options...
Guest PT247 Posted May 20, 2016 Share Posted May 20, 2016 Ah right I might try 0.25g BBs next time and order some 0.3g's. thanks for you reply I'd never run a gun, not even a pistol on 0.2g BBs in woodland, some folk have struggled to lift the 0.3g BBs with their Krytacs so you may prefer 0.28g Link to comment Share on other sites More sharing options...
JBeck Posted May 20, 2016 Author Share Posted May 20, 2016 Thanks im going to try those springs thanks for the advice. I'd never run a gun, not even a pistol on 0.2g BBs in woodland, some folk have struggled to lift the 0.3g BBs with their Krytacs so you may prefer 0.28g Oh right never knew that ill stop using 0.20g ASAP then.

Guest PT247 Posted May 20, 2016 Share Posted May 20, 2016 nothing wrong with 0.2g BBs in CQB but you lose a world of accuracy and range outdoors Link to comment Share on other sites More sharing options...
