I've got a MPX inbound to my FFL. I'm leaning towards a C More for a optic. What is everyone running? I love eotechs but think it will be to bulky

I'm using a T-1 presently. May switch to a TA44.

Works fine for me. M3 on a LT129. Absolute co witness.

Added a Geiselle S3G and a MOE K2. Just waiting on my stock.

Thanks for the suggestions. An RMR is an idea. I want something low profile and two eyes open shooting is a must. I love my eotechs but think they may be a bit bulky. The trijicon reflexes might fit the bill as well. As for triggers, a S3G will be a must and probably a K2. I'm running a K2 on my MK18 and it fits my hand perfectly.

2 MOA H1 in a LaRue mount. Although, If I didn't already have the LaRue, I would put a Bobro on it.

What mount is that riding on? The 33 or 34? I'm torn between a rmr or just going with what I'm already comfortable with (eotech).

I have this one, but it is not cowitness. They have a taller if you want cowitness.

I ended up going with my tried and true eotech xps2-0. I've ran them on long rifles,416's and mk18's and it just works for me. It fits the MPX perfectly IMO. Appreciate everyone's input.

I run an Aimpoint PRO on mine.

I have a T1 but demo'd a MRO over the weekend and leaning more towards that w/ADM riser.

I'm currently running a Trijicon Reflex (green dot, 4.5MOA) on mine.

I'm using DI Optical Raven RV1 red dot. Love the sight, even though it is heavy. It provides perfect cowitness with Sig irons.

How do you like it? I looking for an RX30 or RX34 for my MPX currently. What mount do you run and how low does it get to the rail? Any pics by chance? Thanks for any info.

Running an Eotech 553 on mine. Had it laying around unused so thought I would try it. I thought it would look too large on there but I am happy with it so far.

I would like to know this as well. I zeroed mine at 25 yards, but I am thinking about changing it to a 50 yard zero.

IMHO 50yds because you have a lot less elevation variance at usable distances.

Assuming 147gr sub sonic @1000 FPS and a BC of .212, with a site ht of 1.5"

If you site in at 50, you'll peak ~.5" high at about 35 yrds, and 2" low @ 70.

If you site in at 25, you'll peak at ~25 yds, be ~.8" low @ 50, and 3+" low @ 70

Assuming 115gr at 1300 fps, it doesn't really matter because you'll cross 0 at about 25 & 50 yds.

The RX34 I bought comes with a mount already. I took a potato picture this morning.

It is a lower 1/3 cowitness. The optic itself is pretty big.

I will take a better picture this weekend. Will also try to capture the sight picture.

I ran out of money after buying both the MPX and MCX within a month of each other so I threw an old Aimpoint M2 on the MCX and a bought a new Vortex SPARC II for the MPX. The SPARC II really isn't a let down at all though. It is built sold, has easy controls, and fairly compact.
