Default Re: Ar-10 Bolt Gun

So...

I got an AR-10 annodized upper and lower (80%) matched pair for $160 delivered.

http://customarpartsandkits.com/prod...r-receiver-set (I paid $150 before shipping when I bought mine two weeks ago. Today they're $180 before S&H.)

A few fits and starts later, it's finished.




The barrel is a Carl Gustaf machine gun barrel originally chambered in 8x63 Swedish. http://1919a4.com/showthread.php?255...please-help-id) This is the same barrel I have on my 8mm SLT using the .376 Steyr case. They can be had from Sarco for $40 +S&H.

Here are the procedural steps:
1) Cut barrel breech to fit the chamber length of the .308 Win,
2) Cut a new 8mm throat with my 8mm throating reamer,
3) Threaded it for the AR-10 barrel extension,
4) Installed the barrel extension,
5) Milled the 80% receiver to 100%,
6) Milled the 'deflector' off (that big lump behind the ejection port on the upper),
7) Milled a slot from the rear of the ejector port to accommodate the bolt handle,
8) Drilled and tapped the bolt carrier 1/4-28, (No small feat here, that bolt carrier is REALLY HARD),
9) Made aluminum bolt knob,
10) Assembled lower parts kit (trigger assembly and whole fire control group, safety selector, bolt catch, magazine release, take-down and pivot pins, and butt assembly),
Voila'! An AR-10 chambered in 8mm-08. (That weighs 11 lb 13 oz with a full 5-round magazine.)

It was a little more difficult to do than to write, but the above list covers the important issues. There were occasional outbursts of intense Naval vernacular - like when I broke a tap off in the bolt carrier and when a mill cutter grabbed the lower and yanked it out of the vise - but I didn't break anything, (other than the tap), and I still have all my faculties and body parts intact.

The range is closed today but will be open tomorrow so I'll get it sighted in and post a range report. If all goes REALLY well, I might take it goat hunting next week.
