Small bump. Barrel is supposedly on the way to Lilja.

Yes. 6SA has it back and the upper assembled. He wants to test fire it and have it shipped this week.

Posts like this one help me wait patiently

Just got it in my hands today.

Loading from a mag is perfect. Bolt shuts completely.

Extraction is perfect with 103, 105, and 108 gr projectiles.

Hopefully I’ll be able to get to the range and shoot it tomorrow.

Fingers crossed!

I’m glad to see you got this thing squared away finally. I’m looking forward to seeing how it does!

She shoots pretty well.



Need to get back out with a bag.

This was literally off of a wooden V with a rolled up jacket as a rear bag.

Any reputable person building ars for sale should have go/nogo gauges. I may not check my own but you can be damn sure if I was selling to people I'd be checking before.

Seeing their website I imagine their shop being a small garage.

If that is believable as a cause (not saying it isn't) that's pretty crazy.
Also sounds like gunsmith will be smart to add a step to his quality control.

I assume you're talking about headspace gages.  Headspace gages don't check the throats.  When you buy brand new barrels, you don't expect to have to check that (or buy the gages to do it).

Oh yeah, I got a first round hit (actually 4 out of first 5) at 500 on (36”) steel hold was about 3.6 mils high (14.5” barrel).

Got multiple hits on 12” steel at the same range.

Glad they fixed it for you.

Did I miss what was done?

Good shooting too

Barrel reamer (throat reamer?) was worn out by the time they made my barrel.

Guy I bought it from sent it back to Lilja and they recut the throat.

Probably do a Craddock RTR for my next one. I want a M12-ish 6Arc
