How to tell who made my AR-10T barrel? was created by Gewgaw
Hi all! New member here. Question for all you AR-10T barrel experts! I bought a used, complete AR-10T upper with 24" stainless steel heavy barrel a couple of months ago, and I have been trying to find out if it's a Lothar Walther manufactured barrel or not. The guy I got it from did not know.

Is there a way to find out if it is a LW barrel by looking at it? Are there any sorts of identifying stamps or marks I can look for? I don't have a bore scope, so it's hard for me to tell from the rifling....

If it's not a LW barrel, who else could it be? I've seen Douglas on this site, on Sniper's Hide they told me it might be a Wilson... Any way to tell from the barrel who made it???

gewgaw,

Maker's data is generally on the shank end of the barrel. Rifling type, twist rate, land and groove diameter. I've yet to see a "makers" mark on the barrel itself. Unfortunately, most of this information is machined off during the installation process.
The maker should be able to tell you who's tube was used.
My GA Precision AR-10 has a Schneider barrel. The tube itself is marked GA Precision as the maker.
Not the answer your looking for, but the best I can give at this time.

Thanks for the info! Yeah, Armalite told me they could not tell me which one my barrel was simply from the length and material it was made from, since they had many different suppliers.

Just in case anyone recognizes it from the crown, here's a pic:

It looks like it has 4 grooves/lands.
