I have really like the design and fit of the original JAE, one thing I have noticed is that the handgrip area for your trigger hand looks larger than previous? Is it bigger and can you reduce the size of it?
Call the manufacturer of the can and ask them about cleaning. Doing the wrong method of cleaning may void your warranty. I would ask about the QD also.
I got play with one last week and it was very nice to shoot. Recoil was like 223 and muzzle flip was minor. This was shooting a 6 Dasher. I am seriously thinking about getting one, but it may have to wait after I get new barrel. The high cost is the major deterrent on the purchase.
I bought 1000 105 Hybrids and they all looked like that. Sorta freaked me out, so I loaded up a 100 and shot great from
100 to 1000 yards. No issues at all after next 650 I have shot from that lot.
I would be interested in seeing how you setup it up on your rifle. I saw a couple this weekend at the TBP Scorcher match and they looked cool. The shooters really did like them. My problem is I have almost no place to put it on and the MDT Level on my mount.
Suppressor is going to be your best option. I have tried a lot of them and I have yet to use one that did not have a concussion issue. The best for me is my Ace brake, to eliminate it completely, I use my suppressor.
