MullerWorks bbl - I think

[TAJ45]

Bbl is sold. Thanks to all for the assistance on this.

Unchambered 28", .900 straight measured. Stamping looks like this:

12 o'clock.... MWB

9 o'clock ..... 4G - directly under is M then (1 or I)

2 o'clock ....... ?? (lower case s or g?) before 37.

3 o'clock ....... 16T

4 o'clock ........ SS.

6 o'clock ......... 22 RF

Izzit or izzn't it a Mueller?

PS, shipping tube has Muller 4MI .900. 28"
No addy on tube

I don't know what the M1/I is under 4groove.

Entire 2 o'clock means? Or 4MI on tube for that matter.

My 22/250 has a Muller works bbl . 12" twist its a tack driver .

Not sure what the 2o’clock means. MI stands for minimally invasive meaning shallow lands. Very sought after barrels as demand exceeds supply.

I believe Keith got it right, Muller 4MI.
Hope you have a good use for it.

It should be sold before you log out! It won’t last long!

Dave has got a great 22 Mag reamer he may let you borrow.

I truly appreciate that offer Keith but not enough splat for my intended use.
T. was a true trooper.

Sir is this barrel for sale ?

 

[TAJ45]

Was sold via PM. Thanks for interest.

I spoke to Paul T last night, he said with those markings it was lapped by Dan.
Paul marks the ones he laps a little differently than Dan.
Not that it really matters, they both lap to the same excellent high standard.

Not surprised that it disappeared so fast...

I figured somebody'd get ahold of 'ya before you had a chance to list it.

Well, there is one more. Same box, same return addy on label but already turned for a Turbo per note on box, .0003 taper iirc w the markings duplicated by etching. This too has MI at 8-9 and MU at 12. An R4 profile....2 fat ends I found out today from Shilen. Totally green here on rf stuff, obviously.
No extractor cuts or threads.
No taper.....so properly not what Shilen calls an R (reverse?) 4.
