Well the first of many parts have arrived, channel and gas tube support. No prints yet so I can't check the specs on the receiver channel to see if they are off or not. I look like I will have to do a bit of machining on the channel and I am still undecided if I will do a true M249 or an Mk46. I think that will depend on if I can find a magazine feed weldment or not. Finally found a supplier for trunnion and rear bridge but waiting on more funds.

More parts have arrived. Looks ok...some parts need to be refinished and I will need the guts for the top cover but it is getting down there.

I see a few from time to time on Gunbroker in used condition, but US Machinegun Armory will have them at retail $620.00 I think. I just bought the rest of my receiver parts from them, they are great folks.

Will you be going with striker or hammer fired?

Most likely hammer fired. USMGA has a proven design and the parts not any more expensive than regular FA parts. The weld-up will start after I finish machining the channel. I have to study my prints a little more as I will be leaving out alot of cuts need for the M249 MG and only using what I need for the design.

OK I have been working on converting the metric prints to english cad and I have this so far.
Note the lack of a cutout for the trigger housing group due to that SA part has not arrived so I could not measure to fit. I may omit the OP Spring Guide notches at the rear of the receiver as I will not need them for SA version. I have also left out the magazine feed on the advise that it is more trouble than it's worth. The receiver channel I got was not bent to FN spec's but it will do. |

Here is a few more pictures of the parts and fitting process. I was ready to start cutting the receiver channel today but the motor on the mill died after 12 years so I have to order a new one Monday. Still waiting on more parts but it looks like it will weld up fine.

Here is a few more pics...more parts! Sweet. Just a rough layout to get an idea of the finished product. The fire control group will be SA not the FA pictured, but you all get the idea. All of the receiver parts have arrived. New milling machine motor should be here Wed. so Thur or Friday is cutting time. Top cover guts are still proving to be a pain to get...good things come to those who wait I guess. Nooooooooo I want my parts now! Sorry, I am getting really excited about this build. Realisticly it is still a few months from finished but it looks more like a gun than a pile o' parts now.

Have you SBRd it yet or are you going to get a long barrel for it? I love this project, please keep the updates coming.

I'm going to blind pin then spot weld the flash supressor on to get 16 1/4" from the current barrel. I may register it later as a SBR but I hate to pay another $200 tax when there is such an easy work around. Plus all my other Class 3 paperwork took forever and a day to come back. It would look cool with my 5.56 supressor attached too. But that's a while down the road.
