So, currently I run the Colt and KAK buffers that are the two part with the springy face. I want to try the KynShot just to see what it does. But not sure which is the "right one". The RB5015HD or the RB5007, I'm thinking the HD one, but are their other considerations I am not thinking of that should go with it? @Blowback9 Do you or anyone have a suggestion? These are the 9mm's I have (shameless plug for my toys) 8" barrel  10.5" Barrel  7.5" (I dont recall what the DOE is now.... oops)

@seand1111 Here's a link.....read and gain knowledge. https://blowback9.wordpress.com/ EDIT.....Botach has the best prices on the Kynshot buffers Midway has the best price on the Kynshot additional 2.5 oz buffer weight . |

I run the CMMG RDB (delayed blowback) and like the RB5007 for that. I would probably run the RB5015HD if I was running straight blowback but I prefer delayed instead. I use the same lower for 9mm (CMMG RDB) as well as 5.56 / 300BLK with zero changes as documented here: https://c3junkie.com/?page_id=2757 |
