I stopped keeping accurate counts of ammo through both my MPXs but I'm guessing 7-8000 rounds through the one. There shouldn't be a need to mess with it. I sort of expected this since it was originally the 16" barrel but it'd be nice to have a reference before I enlarge it a bit. It runs flawlessly suppressed but with my Barking Spider I only get last round hold open about 25% of the time. Some attachments require paperwork, so make sure to comply with your local laws and regulations.

To the best of my abilities, I've measured my gas port between 0.050" and 0.055". The MPX has a full-length Picatinny rail on top, and it comes with flip-up iron sights. My barrel was an 8" and I cut it down to 4" threaded 1/2x28ĭid you enlarge the gas port at all? If so, to what size? Its advanged ergonomic shape improves the feel and handling or your MPX. I ask because I cut my 16" carbine barrel down to 4.5" but had it threaded 1/2x28 and run my Barking Spider 2 on it, however I have a factory 4.5" on the way but it just dawned on me the threads won't match. The handguard also includes one five slot M-LOK compatible rail section and a heat treated 4140 retaining clip with a black phosphate finish. Im looking at taking a carbine course at Trigger Time in a couple weeks so ill be in the area.ĭsully, I just realized that you seem to have all genuine Sig parts but that would mean your K barrel is threaded 13.5 x 1 LH while the Barking Spider only comes threaded in 1/2x28.ĭid you have one of the factory 4.5" barrels cut every-so-slightly and re-threaded to 1/2x28?

Thanks brother, I may just take you up on that. If ur ever around Sanford hit me up and u can check it out in person. Honestly I don't even notice the partial slots when it's all together. I did have pretty good luck with attaching bcm keymod covers and cuttin the flush with the end of the rail.

Seems like its impossible to get them cut and have no partial keymod slots or partial pic rail sections. Would you mind posting a pic of your handguard after the chop? Ive seen several of the KeyMod guards chopped and it looks like everyone is cutting them in slightly different places.
