Thanks for the compliments. It's a bit of a heavy set-up, but the features make it worth it. I'll probably get a 20" barrel for it in the next few month as a suppressor host. My understanding is that 22" is really the lower limit of barrel length before blast and recoil get very noticeable. However, the suppressor should mitigate much of the unpleasantries and give back a little velocity while keeping the size reasonable.
My only dilemma is the choice of suppressor. Right now, I have a SF SOCOM 762 RC-2, 300 SPS, SC Omega, and Thunderbeast 338 Ultra. I'm leaning toward the Thunderbeast despite it being a larger caliber.
