Hey guys,

I just purchased a brass deflector for my MP15-22. I use a Primary Arms M4 Red dot.

This is the deflector I purchased, doesn't fit with or without the red dot. The bottom portion of the deflector hits the built in deflector on the upper.

My problem is when I go to the indoor gun range I've got shells flying everywhere and I can't stand it.

Any ideas?

It doesn't fit because it's made for a 5.56 upper. The location and dimensions of the ejection port and location of the built in deflector on the 15-22 are different than a normal AR upper for a 5.56.

Can you modify the deflector by removing material from it so it clears the built in one?

Yeah i could but now that I've got it the rail attachment is really not great. I've already bent the steel fingers that attaches to the MP15-22 without trying.

well how does the brass really bother you. i mean that thing looks completely useless but then again im a soldier that shoots alot and ive never had any issue with brass ejecting that attachment seems worthless.

Maybe a Caldwell AR-15 Brass Catcher will address your issue?

I shoot my 1911 45ACP, no problem, my wife's 9mm SW Sigma, no problem. For some reason the indoor range I use has the ability to have the brass leave the gun, bounce off the side partition and right back at me, the gun and my optic, only with the MP15-22.

I've tried the UTG version of this, doesn't stay open to actually catch anything, folds over and creates more of a barrier.

I couldn't find a pre-made solution I liked, so I made my own:

Materials:

- 1/4" thick piece of lexan
- 1/2" x 1/2" x 3" piece of Delrin
- 4 cap screws
- 1 rail mount - originally was a bipod adapter

The deflector attaches to the handguard. Installs in 2.5 seconds, removes in 2.5 seconds....

You can see in the last picture how effective it is...

A couple of reasons why you might want a brass deflector:

- if your range makes you pick up your brass it saves you time. I don't know about you, but I'd rather shoot the extra 5-10 minutes it takes me to pick up my brass.

- the person sitting to my direct right sure does appreciate it.

- as the OP noted, a lot of ranges have dividers between firing points. Sometimes solid, sometimes wire, etc. I get an occasional bounce-back off the wire mesh that separates the firing points at my range. Additionally, a lot of brass goes through the mesh into the other person's firing point.

- I'm left handed, so I get an occasional ejection someplace I don't like, like down my shirt..


Also, not to sound smug, because I'm a former full-time soldier myself, but how is being a "soldier who shoots a lot" relevant? That kind of comment isn't going to be well received here.

There are many civilian shooters on this forum (and in my local club) that shoot far more often and far more rounds that I'm willing to bet you do in your job as a soldier.

Nice, that is about what I'm looking for. Something simple and not in the way.

i have been clipping an old towel to the divider at the range we use..
stops and drops them in the cardboard box they leave you to put your brass in when done..
clean up is very quick and easy.. no attachments needed

where is a good place to get delrin and some lexan?

Try Modernplastics.com, probably has what you need

Hi, you could try McMaster Carr they carry tons of things from nuts and bolts to sheets of plastic, all kinds of things and they ship. Funny the same thing happened you me last week and I was thinking of some sort of deflector or catcher. I was shooting at the range and my shells were bouncing off the wall next to me and going everywhere!

Amazon actually has everything but it is in foot sheets... More than I need. Both the delrin and lexan.

Check local glass shops; many carry both and all you need are scrap-size anyway. Plastic fabricators are another source.

McMaster-Carr (McMaster-Carr) is where I got my materials, however, you don't need to use Lexan and Delrin. In a pinch, a 1/2" x 1/2" piece of hardwood, ie. Maple would work just as well. Also, you don't need to use Lexan either. Actually, go to Staples and get a clear plastic clipboard and use the plastic from it or from something you may have hanging around.

It doesn't need to look pretty, just needs to deflect the brass.

I'll make it easy on myself, how much do you want for yours? lol

The UTG is not even close to the Caldwell. The Caldwell brass catcher has a rigid support that keeps the mouth of the catcher open. There is also a stiffer material at the mouth of the brass catcher before the mesh that keeps it's shape.

Made one a while back aswell.

cost: $ 0,00 (piece of metal cut from my old computercase and some black flat paint i had)





Holes matched the position of the screws of the EOtech replica. Now i have a CompM4 on it, drilled in a new hole in the deflector and with some 4mm bolts it fits nicely through the raiser of the CompM4

That's a neat gadget you've made.

This Forum has more creative talent than any place on the Net.

I think you had a great idea there.
I just got a MP 15 22 and my son is a left hand shooter so I was looking to help him out and saw what you did and made my own.
