Mashup of a few different BCARs that I like. Good up to 200fps in my experience. Progressive twist, vented, oring mount.

I really liked this well vented progressive BCAR, while building my own I noticed that there was space for an oring in the clamp mechanism that did a perfectly fine job keeping the muzzle on the barrel without assembling the HW intesnive clamping ring, which inspired this remix. I used the oring retention base from my next favourite BCAR; Zafc's Celestial, to enable a tunable barrel fit.
3 orings will give you a very tight fit comparable to worker PCAR on most barrels, 2 orings for a more easily removable fit that feels about as tight as an Ex Rev2 collet, 1 oring is super easily removeable and still fits about as tight as a DZP BCAR. Of course, your print tolerances may vary.
I really like the Hikari 103 BCAR on the new MPP with stock barrel to tighten up the FPS and get way better groupings, or with a 22cm barrel to get it down under 150fps. Seems to give really good groupings up to around 200fps.
