I used their rifle blanks a while back.. OK for the money.. but to mass produced to really be #1.. old saying.. you get what you pay for.. Same with their shotgun barrel blanks.. The worked.. but Hastings worked out far better.. The rifled shotgun barrel for slugs works GREAT.. Service is slow.. but not bad.. They always answer the phone..and are easy to work with..If I were build Sten guns.. or something like that.. their barrels are all you'd ever need.. benchrest.. I'd think Shillen..
