Well.. FINALLY after 1 1/2yrs I have my projects finished... yup.. another OLL.. but this time I did the lower by hand... well.. with a Bridgeport and guidance from my machinist buddy.. it was done without DRO's!!!! :eek: That is one reason it took so friggin long.. that and I took my time and could only do 1hr at a time tying up my buddy's mill.. the Mag well took the longest and the buffer tube threading was the easiest as we used his very expensive lathe. I was lucky enough to have the anodizing(Mil-Spec Type II Hardcoat) done same day (I'd name the shop but they did it as a favor to me as they are good friends with my machine shop friend) Actually I DID have access to a CNC machine but that was for 1/2 hr to CNC a serial number on it as well as the Fire/Safe lettering. Would I ever try it again?? no..... but it is ALL mine and I can say I did it myself...... BUT.... I have to admit I trashed 3 other 0% forgings in the process..all were in the mag well hogging out phase (went too fast and got impatient)

Muther f'ing bad ***! I've got a few of those castings laying around but I like them just the way they are. It'd be WAY cool to say I built it myself, but I don't have the knowledge or the equipment to do it...so I just show off my un-machined M16 to anyone that'll look. :D

Very nice. That could easily pass off as a name brand lower in my honest opinion ;)

I didn't have that much experience at all myself.. (I did real bad in 9th grade metal shop).. I just had a buddy that I have known for 25yrs and he just guided me through it... (I do have a DVD set on milling a %0 foring and he watched them to get an idea so he could show me what do do) but I tell you one thing.. I sure lost a LOT of weight sweating out the whole process!!!) He did teach me extremely well on how to use and read micrometers!!! and some of the other measuring implements needed....at the end of an hour my shirts would be completely soaked!!

There's a few subtle areas that are giveaways.. like the pin hole for the bolt catch.. it's off center, I didn't do that good of a job smoothing out the forging marks in the trigger guard area and on the front tabs for the trigger guard.. I drilled through both tabs instead of only the one tab :o

lol.. sorry.. they got recycled last month... I still have 5 or 6 0% forgings that are untouched sitting here... incase I ever get ambitious again (hardly ;))

Well done. That is some phenominal work! I presume that your receiver is for a pistol build?

I couldn't help noticing, you have ACU carpets!

NRAhighpowershooter
09-04-2008, 9:34 PM
lol.. I didn't even realise that about the carpet!! but back to the big question.. no.. the lower will be used for my Service Rifle upper.. I machined the top deck of the lower to be a tight fit with the upper..

Well.. I MAY have to fit the bolt catch as the off center hole is on the high side and it might make the bolt catch ride high.. no biggie if I have to file a little on the bolt catch.. I can always repark the bolt catch after a trial fitting and filing...

One thing I have found is when you build your own, you know every little thing about it, and it is probably the best way to understand exactly how everything works.

Nice job, so how much cheaper is it to just buy a complete lower?

Nice job, so how much cheaper is it to just buy a complete lower?


Well.... OLL's were in the mid $150's to upper 170's 1 1/2yrs ago ( I think).. and a 0% forging was $25 + $3 shipping... factor in I trashed 3 forgings.. so in forgings I was into it for $100.I had to buy a few special LONG drill bits. The anodizing was $106 out the door. The CNCing of the serial numbers and fire/safe lettering was done as a favor. The milling was done piece meal since my buddy is a one man shop and he couldn't let me use his Birdgeport everyday.....so all in all factoring in my labor and the material costs it is DEFINATELY cheaper to buy a lower......

Thanks :D there were times, though, that 'the Project' sat for months at a time simply because I just wasn't into it.......

Nice work. That's probably too ambitious for most of us but a simpler route would be starting with a 80% receiver. https://www.vbd.com/noc/shop/products_detail.asp?CategoryID=29&ProductID=122

Be sure to pistol mark, even if you think you'll never want to make it one... you never know if someday you'll change your mind. :)

Yes the serial number is of my own creation , I had suggestions from some of my HP shooters, 4 numbers and 4 letters.

so if i get an 80% it is all done all i have to do is drill out the holes ?

You have to drill out the holes, ream and tap the buffer tube, also the fire control group area is undersized. I'm a member of this homegunsmithing site
http://www.homegunsmith.com/cgi-bin/ib3/ikonboard.cgi

The places where you can get these 80% lowers usually say these are the areas that need finishing. One of my HP shooters has a 80% lower and it loks to me that is what needs to be done on his. The nice thing about 80% lowers is the magwell is EDM cut which makes a nicer looking magwell instead of a drilling out the corners and hoggin out the metal on 0%.

I asked the same thing. But it is not too outlandish. Considering no $70 DROS and other fees. And the perk that it can be a pistol lower etc etc.

AR15Plus is where I got mine. Now the hard part, engraving. I am thinking of safe, fire and burst and a homemade logo that I have yet to design. It took about 3 hours to do the drilling and another 1-2 hours to clean up the casting.
