Hi,
In addition to civilian sales in many countries, there are a number of countries utilizing our SL series SL7/SL7-BL and now the newer SL7i / SL7i-BL variants in MIL/LE service.
They are throroughly tested by us and built to withstand the pressures of the magnum calibres for a long life time.
The thread mounting SL7i .300/.338 of course is smaller, lighter and more economically priced than the BoreLock mounting SL7i-BL.
The BoreLock mount provides more secure attachment as thread mounting suppressors do have the possibility of loosening up and if the user wants to shoot only with the muzzle brake, then easier than switching between the thread mounting suppessor and separate muzzle brake.
The BoreLock system itself was made to be a secure mounting system, ie. the suppressor stays on when you want it to stay on but also can be removed easily even after firing hundreds of rounds. The 4-position adjustment on the BoreLock mount allows one to mount up the suppressor tightly, if switching between different BoreLock flash hiders and muzzle brakes,
Best Regards!
