I needed to replace the barrel in my Olympic Arms Ultramatch purchased new in early '93 after an estimated 16K rounds of sage rat shooting.
The gun from the get go was confidence inspiring, especially when everyone back in the early 90's said AR's will never be as accurate as a bolt gun. After about 3 years of being beat by an ugly black gun, my friends began converting and we still shoot together every season, 27 years later. The last 4 seasons the old barrel began to lose it's touch and my bore scope confirmed it was toast. The OEM .223 barrel was 24" button cut heavy flute under handguard to H-bar profile at the muzzle.
After extensive research I chose Krieger and Compass Lake to supply a new barrel in their 22" Varmint profile 1:7.7 twist .930" at muzzle threaded 5/8x24.
After 100 break in rounds of PMC Bronze following Compass Lake's procedures I went to the range last week with Federal Gold Medal 69g SMK to see what it would do. Conditions were less than ideal 40* raining swirling winds. Shot a total of 30 rounds, this is three of the last four 3 shot groups.
