Hi all, looking for feedback on Silencerco muzzle devices.
I have a SiCo Hybrid 46. Using their ASR flash hider on a Sig 516 (AR15) I noticed the flash hider does not bottom out on the shoulder of the threaded barrel. I shot this several times before realizing and there were no effects on accuracy. I assume this is because a .223 bullet has so much clearance in a 0.46 bore suppressor that any concentricity issues are insignificant. That said I understand this is not right and will correct.
Also using Silencerco's 3 lug on a Kriss Vectdor .45. That 3 lug muzzle device does not bottom out on the shoulder either and it has affected accuracy significantly. In fact getting some jacket shavings in the blast chamber although thankfully no apparent baffle strikes.
Questions are: have others found Silencerco muzzle devices lack the internal thread depth to bottom out on the shoulder? For correction is best solution to use a shim? For the 1/2x28 on the Sig 516 there are lots of options. For the M16x1LH of the Kriss I haven't found anything available. Has anyone run into this on a Kriss .45? Kriss Customer Support advises against using a barrel shim and implied the SiCo 3 lug is at fault.
Thanks,
Ken
