Dan Lilja has been an active benchrest shooter since the mid-1970s and began LilJa Precision Rifle Barrels, Inc.. Lilja Barrels have numerous competitions, including events in NBRSA, IBS Nationals, Super Shoot, Cactus, Crawfish and Williamsport, FCSA, BR-50, CBA, ARA, RBA, and even Olympic Gold medals.

Lilja Barrels are so accurate they are often used by US military and major bullet manufacturing companies. These barrels are made from 416-type stainless and 4140-type chrome-moly steels, US tooling, pull-button rifled with a uniform twist, stress-relieved in a vacuum furnace and hand-lapped, and inspected with a video bore scope, Sheffield Air Gauge, and Rockwell Hardness Tester.
