HARDCORE System X Rifles

The HARDCORE series of rifles are built to perform with the best of them, promising to offer the same or better level of performance than you will find from more expensive models on the market today.

Each of these models has its own unique features, with the X1 and X2 starting at a base 16” barrel with a 1:7 twist and black nitride finish coating. The X3 and X4 come with a fluted 18” barrel with the same basic configurations. They all use a LanTac Dragon muzzle break, which effectively cuts back on the felt recoil and improves muzzle control significantly. All of them also come with a KeyMod rail system and are ready chambered in 5.56 NATO / .223 Rem.
