MPA Defender FRT upgrade

Posted by Open-Paramedic5054@reddit | Firearms | View on Reddit | 47 comments

I got my hands on an MPA defender in 9mm recently just because the price was low and ended up loving it. I'd like to look into an FRT for it but haven't had much luck finding one and was wondering if anyone had experience with a similar idea. Thanks in advance!

War-Technical@reddit

Hey I should be able to run it soon. Had some other projects but this is next.

hotrodgreg@reddit

Any updates?

[-]

War-Technical@reddit

Hey gonna go shooting on the 9th. I will test it then. Will keep you updated.

hotrodgreg@reddit

Is it a metal or plastic frt that you bought?

[-]

War-Technical@reddit

The metal from 144.Lame, annoyed cause when I bought, less than 30 days later they dropped an updated that was 20.00 cheaper. They sent everyone who purchased originals the updated like a few days after I got mine. Got buyers remorse so that’s why this dropped to the bottom of my project list.

Well, with the somewhat squared top prtion I would recomend ralound it off just a little, and also pay attention to your safety after 20-30 rounds. It might bend downwards when in the fire position due to the extra force of the bolt pushing the frt downwards. MPA unfortunatly took a lot of material off the safety bar. Im thinking of designing my own that is thicker where the cut out is, and also not as wide of a cut out.

War-Technical@reddit

Ok, good to know! Thank you for the info. Yeah was hesitating to drop into my tricked out MPA build and was gonna wait for the PSA sale on a top cocker, so I can thrash it. I might just wait after learning from you.

[-]

hotrodgreg@reddit

Yea I got the top cocker for 350 through psa. Once I put a brace on it and my obsidian 45 it was stupid fun to shoot. Im planning on making a carry handle that atatches where rhe front and rear sight go, and making a top cocking handle that sticks out to the left.

War-Technical@reddit

Yeah I’m running the strike brace, Huxwrx cash 9k, and the sovereign arms trigger, deltapoint red dot. Tons of fun, eats subs all day, brace is a must. Haven’t had any issues except one single “out of battery” with cheapest Turkish ammo, one out of over 500+ rounds

[-]

hotrodgreg@reddit

I wanted to get the SA trigger to eliminate a lot of the slop, but if I beef up the safety then I should not have to. I really want to get a carry handle mad so I can use a red dot. The tiny ass sights make it a point and shoot gun. But surpisingly fun for the money. Its the c2nd cheapest gun Ive ever bought that was 100% reliable. Well... other than the safety. Still works in semi tho.

The Twitch /Toadlicker556 got one running on my MPA

[-]

hotrodgreg@reddit

Have you had any OBD yet? Was it as easy as installing it, or did you have to do anything to the frt?

[-]

International_Fun_91@reddit

Let me know if you find one….

[-]

Ghost3741@reddit

Found one, but it's a 3d print and I don't have a 3d printer 😭

[-]

International_Fun_91@reddit

Send it over please , I’ll have someone on eBay

[-]

jorazatx@reddit

any update?

[-]

International_Fun_91@reddit

From my experience you’ll find someone online to 3d print it , also found a link to the creator of it but it’s been sold out for over a week already , also ca have a gun store put it in for you also… let me look again

Advance reset tech on Instagram had some videos of an MPA 9mm

[-]

Vurtux@reddit

Would not do any business with this company or any name change company he comes up with

[-]

BMF300winmag@reddit

Their ordering process is pretty fishy, I don’t think they even have a website yet

[-]

Vurtux@reddit

They had a website that was supposedly ddosed and then conveniently changed from advance reset trigger to advance reset tech. Didn’t have an order shipped out until after a month+, several emails and a dispute process. Just to get a non operable trigger in the mail. Would highly recommend avoiding this vendor.

[-]

BMF300winmag@reddit

Agreed that is not acceptable business practice for gear like this

[-]

Livid_Plankton1248@reddit

AdvancedResetTech is making one it’s supposed to be out soon, they have clips on their instagram!

[-]

Vurtux@reddit

Don’t do business with this guy

Mac'n'Cheese or MacDaddy on the Odd See take AR FCGs but I dont think they work with Super Safeties or FRTs still

[-]

GildSkiss@reddit

There are SS compatible remixes of the printable Mac lowers. You just need a trip and a longer lever to make it work.

The main project is for the MacDaddy 2.0 and has printed and metal trip options. I know there's also a DB Alloy remix that uses the metal trip.

[-]

kapitalnoir@reddit

Just the face of the bolt on the side where the trip bar sits, correct? How much did you sand it?

[-]

GildSkiss@reddit

Not the face, but the underside of the bolt, all along where the trip is. I only had to do a little bit. Obviously you should do a little at a time, and stop when the action gets smooth

[-]

kapitalnoir@reddit

Yeah, the bottom of the bolt where the trip would be. I don’t know why I said the face lol …

Cool, thanks! I actually see that they mention 0.015” on the instructions for the SAS-9 kit (which is the same kit)

SavingsAdditional996@reddit

1441recoilsystems has some in stock, a 3d version and metal version

[-]

DisagreeableMale@reddit

This gun is fun to shoot but I'm having a hard time finding attachments other than a brace.

[-]

TreemanOSB@reddit

I put a 6" barrel extension from American Machine Gun & a triple pic rail handguard from Masterpiece Arms themselves, along w a Strike industries brace + Holosun optic & a laser/light combo. Luv this thing...for the $, it's my favorite gun to shoot of the 13 that I own.
