I can certainly relate to wanting to minimize trade offs. I should elaborate. My very first suppressor was an AAC 762-SDN-6. It’s over 7.5” long, 22oz, plus 4oz for the mount, has minimal blowback, and is super quiet. But it’s H-E-A-V-Y. And the mount sucks. I used it for a few years and put around 6000 rounds of 5.56 and maybe 500-600 rounds of .308 through it. I took several defensive carbine classes and let me tell you, it’s 100% worth a few decibels to reduce the weight, so I ordered an AAC 556-SD. While waiting for my stamp to come in, I took a local carbine class and a month later I took a class by Steve Fisher. Both had round counts of a little over 1000 rounds and I never removed that 762 can. When I finally did, it was completely carbon welded onto the mount and it took a vice, a blow torch, and a breaker bar to remove the can from the mount. And this was AFTER I used a set of vice grips to unscrew the can/mount combo that was pinned/welded to my barrel. Needless to say I lost a lot of faith in the 51T mounting system.
Going back to weight, the 556-SD is about 5oz lighter than the 762-SDN-6, and the difference is VASTLY noticeable when shooting the gun for 8 hours straight. But at 17.5oz plus a 4oz Mount, that’s 21.5oz on the end of the gun, which still gets heavy. So I eventually bought a Gemtech GMT-Halo. It’s 12.4oz on top of a V7 Weapons titanium A2 mount for a total of 13.4 oz. that’s about 8oz lighter than my 556 AAC, 13oz lighter than the 762-SDN-6. It’s about 4dB louder than either one and I can’t tell a single bit of difference whether I’m using heating protection or not. The mount has this far not gotten welded to the can, either.
My Griffin M4 SDII and Recce 7 have also never gottten stuck. Both have less blowback than the AAC 556-SD, making shooting more enjoyable.
This is just my opinion, but most suppressors do a pretty good job of suppressing noise. I’d rather have something lightweight, fairly short, that won’t fuse to the mount.
