Hello all, I’m working on an FRT for the MPA Defender (unsure if it will work with other Mac’s). Minimal testing has resulted in success, and I have begun optimizing. No promises on perfection though. I’m working with TinkerCAD, a bent tape measure (yes, calipers are cheap, but I’m cheaper), and a LOT of trial and error, all in the name of losing money faster. I don’t have anywhere close I can live fire test it (except for an unsupervised outdoor range where I was able to sneak a 3 round burst off that went great), so it’s going to be a little bit before I can (but before the 12th because college starts back up). What I want to ask you guys is if anyone would even be interested in this project? And a little bit of licensing advice for someone who knows little. Through my research, I’ve found CC BY-SA 4.0 to be the best license as (to my knowledge) it allows free download, remixing, gives me credit (I’m the one that went through all the filament and time, plus it’s free), gives people the ability to print it or make it from metal and sell it. And prevents people or companies like rare greed from stealing it and claiming it’s theirs and monopolizing it or putting the files behind a paywall. (Yes, I know it’s not anything as big as Hoffman Tacticals Super Safety, but I still don’t want the potential of it getting stolen). Any help or insight would be appreciated!
TLDR I’ve designed an unfinished FRT for the MPA defender. Requires more testing. Asking if anyone is interested. Asking if anybody knows if I should license under CC BY-SA 4.0 to protect against any rare greed type problems.
Hell yea bro! id love to test with my big mac
Would be happy to test with the PWC 9 if you want
Heck yeah, that would be awesome. I still have some design tweaks and I want to live fire it with more then 3 rounds but once I’m done and have released it I’ll make an announcement. Thank you for being willing to do that!
Did you have to do any modifications to the mpa lower or is it basically stock?
No permanent modifications. Just take the safety selector out, slide the FRT in and reassemble. I should mention it will not be 3 position. Just safe and FRT. I’ll also add an install video in the files when I release it. If you have any more questions feel free to ask.
Absolutely hit me up when ready.
I’ve also designed a mac11 recoil reset trigger. I haven’t had a chance to test it yet, but I think it’ll work.
Mine is a drop-in trigger replacement.
Dude I’ve been waiting for someone creative enough to come up with this. I have a vmac and am praying it will work with my setup.
Thanks man. I really hope it works for you. I think the main deciding factor will be safety selector size and location matched with the upper/bolt geometry. I’ve only ever even seen the MPA defender clone so that’s all I have to go off of, but if it doesn’t, I hope someone will remix it to work with all of them. Fingers crossed!
