144LSB barrel roll marks- a question for those with time



Log in to see fewer ads
Hello All,


For those with 144LSBs that have 27.2" barrels, when you have time- could you measure the distance between the receiver/barrel seam and the rollmark?



I am trying to figure out what happened to my rifle before it became 'my' rifle.

IF the rollmarks are all in the same place on the barrel [which seems logical, but doesn't mean it is true], then I am confident in what happened to my barrel. Not why [choice or repair], but what.


So, if you are willing to help out, the next time you feel like pulling out your Mossberg 144LSB, please let me know what the distance is between the rollmark and the receiver edge.

Rosscoe has already helped with some direct info that put us on this track, but getting a sense of if the marks are uniformly stamped, or if the marks 'wander', will help lock down our theories.




I don't want to give away too much of what we found until I get more data for the comparisons. However, I will post that info later to explain how all of the info you provide was helpful.


Thank you!

I took my 144 LSB out and tried to measure but my eyesight is not that good so I filled the roll stamp with white paint and wiped off the excess and polished the area back up. I measured from the receiver/barrel seam to the C in the inc at the end of the Mossberg name and it was 3.5". I could probably pull out my older model but it should be the same.

Mine is 4 1/2 inches from inc to receiver/barrel seam.

Also wanted to mention to OP! My LSB is a later model with serial # and Ak kro groove barrel.

I should go back and check if mine says acro-groove. Neither of my LSB's have serial numbers. I went back to recheck my measurement and it's actually 3.75". I thought the line on the tape measure was the half inch point and the barrel does show acro gruv (can't remember the exact spelling.

Edit to add: I went and checked to older LSB and the C in inc is only 3 & 3/8" from the receiver.

I have a like new LSB barrel that was removed from the receiver.
When I get a chance either today or tomorrow I will dig it out and get a measurement.

Can you do a picture of the shank?

Semi- closeup of shank. I'd like others to see what they're dealing with when removing one of these barrels!

That will work. Then I'll text pic to Wife's phone, then she'll send to email, then I'll copy.

Thanks to all who have chimed in so far!

22_Boomer, your measurements are very helpful- as mine also has no serial number. Better comparison of 'like to like'. On yours, is the overall length truly 27.2" though?


Ross- thanks, as always!



LarDaBear- Thanks to you also! Any idea if the barrel was removed from a serial numbered receiver- or a pre-serial number version?

Also, when taking pics, can you give the measurement that would equate to roll mark to receiver edge?




Everyone else- please, join in!

I'll be honest, when I measured the barrel length I thought I came up with 27.25" but with the barrel slightly recessed in the receiver I'm probably off. I could maybe measure from the receiver/barrel seam to the muzzle I don't know if that's any help.

Not correct measurement........

Measure from muzzle to end of chamber.
