This was my 2nd barrel for my MPX from Robert and ILWT. I wish I had ordered the 4.5” tri lugged barrel sooner than this. Any concern I had about the shorter barrel not being as accurate was completely gone after the first range session, In fact this barrel is more accurate than the stock barrel.
Robert is always great at helping and answering questions. Since I have a griffin tri lug mount I was worried if mine would fit. I messaged Robert and he had me take a few measurements and said I should be good … and mine fit perfectly!
Can not recommend more.
