I have a M-15 SPR with a 20" barrel I got about 2 years ago. I cant tell if its chrome lined. So are all your barrels chrome lined?

If you got it about 2 years ago it's made of 4140 steel, chrome lined and double lapped. The AR-10 standard barrels are the same. Our current M-15 standard barrels are made of Chrome Moly Vanadium per current mil-spec MIL-B-11595-E and double lapped. Our M-15 and AR-10 stainless steel barrels use AISI 416R SST and are triple lapped.
