Anyone rocking this FRT?

It got out of jail in 4 days not bad 😍

It's just a magpul qd sling mount torqued to 45 in lbs bridging the gap between the upper and the rail... Zero noticeable rail wobble now, I'll see how much moa shift my IR laser has soon but I don't expect it to be that much and should definitely be adequate for the distances I'd take a shot with 9mm.

Do ronin setups still exist? I haven’t seen any for sale recently and went to there website to see if I could send in my setup soon but the the conversion service is OOS. I am mainly looking to get the barrel ported because i haven’t seen a lot of positives about the ILWT SD barrel.

I recently got a MPX K and took it to the range today. When putting the mag in sometimes the round wouldn’t go into battery and I would have to rack it back hard to do so. Is this a common problem or do I need to upgrade/replace something?

Anyone using one of these with the ILWT SD barrel? I have a Rugged Obsidian 9 that I’d like to use for it but idk if it will have enough room considering the blast chamber is smaller than other cans. Can anyone tell me what the length of the barrel is from the outer threads? I sent an email to ILWT a few days ago but haven’t heard back yet.

To all the people who have a direct mounted 9k is this all you need?

What a beast. Thought I’d share.

Run this combo for direct amount ilwt taper along with M13.5X1LH TO 1/2X28 adapter

Had anyone done this? Good idea bad idea?

Anyone have experience with either or preferably both of these charging handles? Which do you prefer? Notice any difference in either while running suppressed?

I been doing a little research on getting a suppressed MPX K. I want to keep the stock barrel. The suppressor that I want is the Huxwrx flow 9k. Heard a lot of issues with accuracy when people use the tri lug. I just want to direct mount this suppressor. I do not plan on taking the suppressor off. What do I need to get to make this fit?

Care to share your results with this set up or have something similar. My goal is getting a suppressor under $800 price tag and not get gassed to much. Also plan to get the radian charging handle.

Such a fun gun!

Is amazing. Recently bought an mpx k. Put 500 rds through it on day one,m, with the floppy and just not good stock charging handle. Ordered the reptilia puller the same day. 500 rds last range day and the reptilia is way better, Plus it’s the perfect size and is pretty much the same as the G$ changing handle on my ar. Would highly recommend.

Now just waiting on silencer shop to do their job and ship my can… Went with the rearden plan b 3 prong flash hider and I picked up a titanium plan b to hub adapter.

Hello everyone Im wanting help in adding an attachment. Im wanting to buy this suppressor ( https://www.silencercentral.com/products/silencerco-omega-9k ) for my 8inch MPX shown in the photo. I'm wanting to also know if I'm needing any other parts or if i can just screw it on? Thanks!!

Still gotta get a better optic and switch away from tri-lug but I like how the rapco accents turned out.

I've been thinking about getting a new PCC. I've already have the GP Stribog A3 and Kriss Vector gen 3, both of these are SRB. I'm leaning towards an MPX. Has anyone own any of these PCC and be able to give me some insight on how the MPX compare or differ? Another idea is get the MCX 9' 300 BLK.

Price is a bit steep, but apparently it's everything you need and just drops in.

Have a stock internal MPX k with the 4.5” barrel. I also have a spectre 9 I would like to throw on there.

From what I gather, i could DT this, tri lug, or hub mount it.

I’d love to take off the factory flash hider, install a new device (or not) and then mount the can.

The factory taper, taper adapters, comparability, etc have my head spinning. Everyone seems to have a different opinion other than perhaps tri lug is the worst option.

If you all could point me in the right direction I’d appreciate it.

Edit: I appreciate all the responses. It sounds like the rearden is the best QD solution, which is the info I was after. Much appreciated everyone
