Maybe you guys missed the part about shorter and lighter...
There's got to be something out there besides the TBAC
Most 338 cans are geared for 338 LM / NM or similar. Shorter and lighter isn't a great mix for suppressing 90+ gr of powder.
Not all that many 338 options out there. I'm not aware of any shorter (under 9"), lighter 338 cans besides the Crux, mainly due to how majority of the 338 cans will be used on a LM or NM, possibly larger powder capacity cartridge.
Griffin Armament does a lightweight 338 can, 7075 body, that is light but still over 9" long. I'm not sold on a 7075 body personally.
Sig has a 338 but 9.5" long.
AAC, SAS, SiCo, SF, Liberty and I'm sure a host of other smaller mfg'ers make 338 cans so you have options.
There is a reason for not many short, light 338 cans.
There are not many options for a sub 9", 338 can. If the Crux Ark 338 fits your criteria, or the Crux Saxon9, then get one and report back on performance, durability, suppresson, etc.
TBAC is dang hard to match, much less beat, for performance, quality of their suppressors, customer service and employees.
