Hiperfire AK Main Spring Features The Hiperfire AK Main Spring is built using a tri-twist music wire construction a design intended to deliver consistent tension and a hard positive reset when paired with Hiperfire s popular XAK series triggers. This main spring is engineered to work specifically with AKM variant rifles accounting for the mechanical differences found across various AK platform builds. A roughly 2 plus pound pull weight target gives shooters a noticeably crisper trigger feel compared to many factory AK setups. Because AK rifles vary from receiver to receiver with no single mil-spec standard Hiperfire notes that actual pull weight and feel may differ slightly depending on the specific rifle it is installed in. Beyond its use with the XAK trigger line this main spring is also compatible with other stock and aftermarket AK fire control groups giving it broader utility for shooters upgrading an existing trigger setup rather than installing a full XAK system. The hard reset characteristic helps shooters feel a clear repeatable trigger break shot after shot which benefits both practical shooting and precision applications. Finished in Black to match typical AK fire control components the spring installs as a straightforward upgrade part. For AK owners seeking improved trigger feel without replacing an entire fire control group the Hiperfire AK Main Spring is available for sale at GrabAGun.
