I have MPX and an Advanced Armament Tirant 9S suppressor. I beleive the Sig MPX barrel treading is 13.5x1. Should I get a 13.5x1 LH piston and a fixed barrel spacer or go with a 3 lug mount along with an AAC Tirant Triad adapter?
Or, would you go an entirely different route?
If you suggest 3 lug, can you please recommend where to purchase the mount and adapter from? AAC is out of stock on the Tirant Triad adapter and so far, I have not found any 13.5x1 LH 3 lug mounts.
Also, I know I already asked this in another thread, but have not had any reaponses thus far. Will a B.A.D. Lever work on the MPX?
