m&a parts advertises that their barrels are wilson math grade. j&t does not say nor does modile 1. does any one know who makes their barrels or how good the wilson is and how the others compare. and also what does chrome moly mean. i see this allot on those websites thanks for the help

I contacted them both by email, and received rather prompt replies.  I believe that both J&T and Model1 both use Shaw barrels, but I could be mistaken one one of them. Just email them and they'll tell you.  I cannot atest personally to Wilson barrels, but the RRA upper I am getting uses the same.  And chromemoly is one of many types of barrels, it refers to the type of steel, however do not confuse it with Chrome Lined, as these are different things.

thanks hershey

It is there in the J&T catalog, they use E. R. Shaw barrels.  DPMS uses Wilson barrels.  I don't know who makes Model 1 Sales barrels, it is not stated in the catalog.

I posted this pic on another post but I'll do it again.

This is a group from an M&A chromoly, Wilson barrel. 1:9, using 68 gr Hornady BTHP, 100yds, wooden bench, and harris bipod.

This is the norm not the exception. It shoots Win. 45gr BTHPs very well too.

I'm pretty satisfied with it.

I have J&T barrels on two of my AR's. To say "accurate" would be an understatement. They also have the best finished bore of any barrel I have seen (very smooth, very shiny, and clean up easily).

I understand "Wilson" makes barrel blanks and lots of people chamber and finish their own barrels. If that's true, quality could vary quite a bit and having a "Wilson barrel" really doesn't guarantee much of anything.
