I know someone on here mentioned building a mini mac, just looking for some insight. Built my first M11 from weld parts and a cobray parts kit last year, now I need a new project. I'm thinking of doing a mini in the style of the MPA mini, or perhaps a carbine. If anyone knows the...

Pretty sure cobray.com has the sideplates and center sections. I know they do for the m11. I've seen flats for the 10 on gunbroker, I had a feeling they were only for the full auto, but they should work either way, as long as you install all the proper semi parts. Are you sure it's not an m11...

Wow! Didn't mean to turn this into some serious shit. Just to clarify, theres no fraud here. I pay my own tuition and expenses, I don't get shit for grants (free money). I do take loans, which I use to help me with my expenses. I have NO health insurance, my wisdom teeth hurt 80% of the...

Yeah I own budget semi auto. Looks like I'm between hammers from usmachinegun or ftf.

As soon as I finish college I'm getting a trust, then all the goodies should start filling my cabinet. Til then no cans or SBR's. I suppose my homemade mac is probably going to be my only mac until I venture into the world of NFA regulated guns. Can't wait! It would be kinda fun to put some...

Well the whole pinned barrel ruining threads thing is making me think about whether or not I really want to replace my barrel. Maybe I'll wait til I can get a new upper too.

Well gold is like the ultimate anti-corrosion coating. I suppose if I had the money to drop on an FA I might consider a gold mac.

I see nobody else has chimed in yet. You seem to get that with anything related to a semi around here. Kinda off topic.... I don't know how long you've had your m11, but watch out for the cobray cast parts. My parts kit I used in my build appeared to have almost no use if not new. There were...

My PM11 upper has the pinned barrel. I don't know the production date. It was my understanding that all of them have pinned barrels. Maybe someone put the barrel in your upper and didn't pin it. I don't see it being a problem on semi auto.

I just love the idea of bringing something futuristic to the relatively archaic technology of firearms. So are you using a kit specifically for a round counter, or is it just a kit that you are setting up to work as a round counter. I love electronics projects. If I still had my ak I think...

Thanks! Once I figure out what to do about a new hammer I'll be ready to rock n roll again.

My hammer snapped in half today. There was an area of black metal inside. Almost like the parkerizing got into the casting. I'm trying to decide on a replacement. Us machinegun has a cnc hammer for $40. Mpa has a hammer for $14. With the mpa I would have to replace the pin and drill out...

It works!!! Finally got out to my friends land today and test fired the mac. It worked flawlessly for about 6 rounds. The trigger hits the safety a little to soon, sometimes it won't fire. I'm gonna take a little metal off the underside of the trigger. No FTE's or FTF's, but the hammer...

Good call on the ruger. Actually I thought the MPA 22 was over $500, which I would never pay for ANY 22. I've always liked rugers anyways.

I've seen that MPA makes one. Looks like it's a mini though so none of the parts would interchange.

Does anyone know of a .22 conversion for us semi shooters? I'd love to squeeze a little more versatility out of my new mac.

all done.... for now Well I got the lower mostly cleaned up, made sure all the parts fit, and hit it with a coat of krylon. Hopefully I can get to the range to test fire it shortly. Magazine still fits too tight, but it won't fall out, and it looks like it'll feed just fine. If everything...

I've got the fire control group fitted and functioning. Still need to drill the rh hole for the safety selector a little bigger. Not sure how the magazine will function. It fits... tight. So ill just insert it with the bolt closed til the feedlips contact the bolt. Pretty sure it will feed...

I bent the feed ramp down a little bit and smoothed it out with a file. The upper fits better now and the bolt is functional. Everything seems to be cleaning up pretty good. I guess I overdid it with the welds on this thing. A quick pass over the seams probably would have been sufficient. I...

I picked up some flat stock and fabricated the sight from a blueprint I found on this site. Got it all welded up, just in the process of cleaning everything up now and doing some fine tuning. Plus I've got about 4ft of steel left over to work on an optics mount. My vision isn't that great...
