I am considering units from KAC, Gemtech & B&T/CCF Swiss, and need some fact-based info. &/or personal opinions. The suppressors of interest will be for both my M4gery (.223 cal) & USP (.45 cal). I have narrowed the selection for each gun down to 2 choices, as follows:
.223 cal suppressor options
1) Gemtech "M4QD" - These have an excellent reputation, and a unique, user-friendly "bi-lock attachment mechanism.
2) KAC "QD" - Currently used by the USMil, but I've never seen these firsthand. Are they as robust as the KAC .45 unit?
.45 cal suppressor options
1) KAC - These are also in use by the USMil, and having just handled one today, I was impressed with their robust, all steel construction. Also, I like the index adjustment feature. Except for access to/removal of the Nielsen device, they can not be dissassembled further.
2) B&T/CCF Swiss - These are reputed to be excellent, can be completely disassembled for cleaning, and have machined baffles, the one nearest the bbl. being inconel. Also has an index adjustment feature. One concern is that the outer tube is made if aluminum instead of steel. Another is that H&K states that use of the CCF Swiss voids the warranty. The Swiss mfg'd B&T is warrantied by H&K, but its CCF Swiss copy, made here in the US, is not. Only KAC's unit is.
If you were faced with the same issues in both cases, how/what would you choose?
