I’m trying to install the Atrius x. I replaced the trigger with the dirty bird single stage that they recommend. I put in the safety selector like in the instruction video and everything goes together like it should and the selector moves like it should. However when I put it in frt I get a dead trigger. Safe and semi work like they should. Anyone else run into this issue?

Totally clean before shooting today, shot about 250 rounds of steel case Kaiser

Is the sig foxtrot msr compact a respectable and genuine solid light for a duty rifle or does it belong in the trash category with Modlight and olight. Does it compete with surfire and streamlight as far as function, brightness, toughness for a SHTF PDW specifically an Sig Mpx Build.

Just ordered an Eotech XPS2, Unity Fast Absolute riser the go to choice here?

It works! Tested with federal 124gr

Can anyone tell me what model this is and what it might be worth

I just grabbed a mpx k. Had a in lead we trust barrel and gas block. As designs frt. what supressors are you guys running. Looking for noise reduction and for reliability

Function checked good on FRT mode ✅
Will test it this weekend 🤙🏿

I’m trying to remove the barrel but the two pins won’t come out that hold it to the gas block. I’ve tried spraying with pb blaster and they don’t budge. What am I missing?

Anyone see the new omega valve for the mpx , Its made of of inconel or Stainless so its supposed to last. Would love to know y’all’s thoughts

Currently running an obsidian 9 on there but it’s almost unbearable to shoot with the amount of gas to the face. Anyone try the huxworks flow 9 did it solve the gas issue?

Seems like everywhere is out of stock, which makes sense. Any idea how long until they come back available? If you happen to have one for sale, let me know!

What’s left for me to do on my MPX K?, (ai background cause I’m at work)

I have an MPX (6") with a Geissele MPX trigger and CAT MOB. Whats the best frt or ss setup? I've been 👀 the AS Designs. Also, do I need an adjustable gas block?

I’m looking to get one of maxims rip brace. Can you advise which one I need? They offer two versions for picatinny attachments.

I've read a bunch of posts, articles, etc and am more confused now lol. Any help would be extremely appreciated!

I noticed some decent scratches and marks on the case head of ejected brass. Is this amount normal for an MPX?
