The Kolar AAA/Sub-Gauge Inserts are designed to maximize sub-gauge performance and pattern efficiency. Max AAA’s are matched weight and balanced. They feature extra-long forcing cones and over-boring. CNC honing ensures precise bore sizing, perfect concentricity and exact P.O.I.
The extractors have been redesigned to handle a wider variety of sub-gauge ammunition. Increased wall thickness and newly designed extractor radiuses virtually eliminate cracked chambers.
Nominal weight is 10 ounces per set. The actual weight of a tube set depends on both the barrel length and bore diameter of the gun. Carrier sets are matched weight and balanced.
