heat treat came back today!

[arjacobson]

Just got some parts back from heat treat today. Single shot 50 bmg

Looks like a great project. Self designed or ? Do you have a write up on what you have done so far?

[arjacobson]

Yep maadi style bull pup

[tomme boy]

If you get it done this winter, I have a place we can go about 900 yds. If we go at an angle, about 1200.

Tommeboy-Sounds good to me..ps message me your address as I have some 30 cal gas checks that should work better for you than the batch I sold you awhile ago..free of charge!!

What rockwell number on the receiver?

[W.R.Buchanan]

Like to see the locking lugs in the receiver. And how did you broach the bolt races or are they just cutouts on the front ?

Also what material?

Inquiring minds want to know. More pics would help.

44 Rockwell on the receiver-4140....bolt is 4340 at 46rc. firing pin is 4340.everything else is 4140 with rc from 42 to 46 depending on part. BTW rifle has been test fired 9 times now. I am finishing the muzzle break this week. I have a steel scope mount to machine and then she gets paint. The last two test rounds were shot from a bench without a muzzle break sitting down.... NOT recommended

I have one of these almost finished. Just need to have the small parts heat treated. I like your grip, might have to change mine.

Ok, the pieces looked good, but how bout a glance at the whole thing?

Here you go- Scope was just used to align the mount. It will NOT be used for the final end project.

[USAFrox]

Wow! How much does something like that cost? For all the parts and heat treat?

[arjacobson]

I lucked out and found a guy who had the barrel made already. I gave 300 for the barrel and he threw in the 4140 for the receiver and the 4340 for the bolt. I have another 100 or so in the rest of the material. The heat treat with shipping was $98. Paint kit was $38-buttstock pad was???. Barrels usually run around 5-600. You could probably build one for $750 if you shopped around and found a good deal on a barrel??
