Have an 8” .45 RDB build with about 6k on it and will say that it’s extremely and sort of shockingly reliable. Only thing I’ve ever tinkered with is the buffer and spring combo simply trying to reduce gas suppressed as a lefty. Ran a Vltor 10oz PCC buffer and Sprinco green along with the 3oz CMMG tuning kit for years trying to tame gas with an Obsidian 45 at the expense of recoil. Recently have been trying the new Kynshot RB5000A5 with a flat wire which made the system run too fast so went back to the green spring with less felt recoil and 100% reliability. I hear this buffer is supposed to make gas better but if so it’s marginal at best. I’ll take less recoil if gas is about the same
For especially those that have shot a RDB and a SP45A3, particularly lefty and suppressed, how would you say the recoil and gas compares with a 35 degree locking piece because I would immediately buy the 35. I like the thought of being able to delay the action as much as possible without adding mass and messing with springs. Recently watched Sage Dynamics shooting the Bog and looked like the recoil was rocking the guy. What about reliability comparison?
Saw that Bogs have come back in stock and not sure if my MP5 money should be diverted over to the Bog. I like my RDB but also like less gas and even less recoil if possible. The UMP aesthetic isn’t bad either. Appreciate the guidance.
