Gunsmithing M700 Barreled Action fitup. Start to finish.

[LRI]

A job came in that had what most would consider an ambitious timeline. Take a new-in-the-box M700 and build a tuned up barreled action from it in 2 days. Not impossible, but your going to be hustling. Due to be ready by CoB today. We open at 8am and close at 4pm. Mtn time.

Now, complicate it. Was out of receivers and they were a day late due to a winter storm. We started at 10:30am this morning. In addition to the blueprinted receiver/bolt, barrel installation, add the following electives:

1. Time/Tig/solder
2. 8-40 base holes
3. Pinned lug
4. Bolt fluting
5. Tac knob
6. M16xtr install
7. dual ejectors
8. Bush the firing pin and turn to 1/16"
9. Thread the muzzle
10. Fit a thread protector
11. Engrave it
12. Spin polish it, t
13. Side Bolt Release installation
14. Test fire
15. Call client to tell him its done.

How long? Pick a number. Would the deadline get met? You decide.

We just did all of this. 3 hours, 37 minutes. Start to #14. I've not called the client yet.

So, here we go:

1. Intake/Log in.

2. Hone receiver:

3. Setup and machine in 5 axis.
3a. Machine ring face
3b. ID bore
3c. Thread mill to 1.085-16
3d. Chamfer ring face
3e. Higbee cut lead thread
3f. Drill for pinned recoil lug
3g. ID bore base holes for 8-40's
3h. ID thread mill base holes to 8-40
3i. Machine for Side Bolt Release

Simultaneous to this being done:

4. Blueprint bolt head
4a. Probe and square the face
4b. Square the lugs
4c. Square the nose
4d. ID thread mill bolt nose for M16xtr bushing
4e. Thread on bushing and solder
4f. Finish machine bolt nose/bushing
4g. Drill for 2nd ejector pin
4h. Machine for M16 Xtr slot

Vetted processes, great staff, and quality machinery. We can't do this every day, but I think we've proven that LRI is the fast tract to getting quality results in a timely fashion. (edited so that my foot was only halfway down my throat)

Happy to help.

I also machined the ramp for ARC Magazine use. Forgot to mention that and take photos. That was a couple hours ago.

So now you'll be a victim of your own success. How many will show up at the shop at 8 am, action in hand, asking you to fit a barrel, blueprint, and true everything? And they'll want to pick it up at 4.

Hopefully about 10 per day.

Hopefully about 10 per day.

This work is kinda like race cars. You can have fast, reliable, or cheap. But you only get to pick two.
Chad just showed us fast!
The LRI reputation for reliable results is uncompromising.
We won’t ask about #3.

I was quoted 12-16 weeks to get the same work done when I emailed in September.

Hopefully you weren't to gentle with the pricing on a rush job like that. ?

Rush Jobs like that are really easy to mess up.
