Today Brownells announced they too are now carrying KRIEGER CRITERION AR-15 BARRELS.

The CRITERION BARRELS are one of, if the not best values in AR-15  BARRELS often shooting as good or better than much more expensive MATCH BARRELS from premium barrel manufacturers. These barrels are a safe bet for any AR15 build. Just ask owners of Fulton Armory rifles.



Criterion Barrels, Inc. was started in 1999 from Krieger Barrels, Inc. in response to demands of rifle builders and firearms manufacturers for quality match grade barrels at a lower cost.

Achieving Match Grade AR-15

Criterion rifle barrels are match grade. Our 30+ years of experience and shared history with Krieger have given us a true understanding of what match grade means. Uniformity of the bore dimension, groove dimension, and twist, along with the finish produced by hand lapping are essential for the ultimate accuracy of the barrel. With our expertise we are able to control these factors and deliver an unbelievably accurate match grade barrel at a reasonable price.
