2025年2月20日 · I've been looking to get a MPX K but can't find one local, MPX copper head is available. I know there are some differences between them but is the Copperhead good to go suppressed?

2020年6月18日 · The mpx-k and copperhead-k are the exact same gun parts wise, both have 4.5 inch threaded barrels, timney trigger etc the only difference is the mpx-k comes with the helicopter folding arm brace, the copperhead has the telescoping brace, both can be easily swapped to whatever you want as they have the same rear 1913 pic rail on the rear of the ...

2021年7月25日 · I’m interested in an MP-style PCC and the MPX is a strong contender. I’ve been through various threads on here about the MPX, but I was hoping you “smart guys” (and gals) could give me your experiences (good, bad, and other) with the MPX. The MPX would be in competition with an H&K MP5 clone...

2024年12月30日 · I have the MPX Copperhead K 4.5 and changed to a Sig folding brace (didn't like the sliding style). I added a Trijicon RMR on a Scalarworks mount with Troy folding BUIS and a Lantac Dragon Dead Air KEYMO muzzle break.

2022年2月19日 · Hello All, After many months of digging and reading I have decided to move forward with a Sig MPX K build. It seems the general consensus is that the MPX has accuracy issues when suppressed with the original barrel, specially if you go with the Tri-Lug adapter route. A solution that is often...

2020年4月21日 · The MPX-K, like all MPXs is gas operated. Gas operation makes the MPX a "soft shooter." When a muzzle device like a suppressor is added, the gas pressure is increased. This will cause an increase in wear on the fire control group and change point of impact. Heavier recoil springs and/or reduction in gas pressure may be called for. ILWT sells a gas plug that …

2020年11月3日 · The MPX-K has about 3.5 inches on the bottom of the handguard which included one 2 inch M-Lok slot and one .75 inch short slot behind the front slot. On my K I have a 2 inch long Streamlight TLR 8 laser/light combination. My …

2021年12月2日 · I am planning to buy an MPX 4.5" manufactured in September 2021. I have been doing a lot of reading but I'm still confused as to how many generations there are of the MPX. I've heard two and three. The reason I'm asking is because I've read that some have had hydrolock problems and some have had...

2022年2月11日 · The MPX is theoretically multi-caliber. When they were introduced, SIG promised caliber exchange kits for .40 and .357 SIG, but they never materialized. My MPX-K hasn't produced the pinpoint accuracy of others, but it is functionally accurate. In other words, solid torso hits from 75+ yards are no problem with a 1X red dot optic.

2023年10月24日 · I’m waiting to get my MPX K and going to Form 1 it to be SBR. I’ve been researching some Upgrades to the MPX K and would like some feedback and suggestions please. Not sure on what Brace/stock and if I want to replace the Handguard. What red dot would you suggest for it? So far I think i’n...
