Took it to the local range and was impressed with the accuracy at 100 yards. The trigger felt a bit heavy for my preference, which slowed down my follow-up shots. Otherwise, it functioned flawlessly with various 5.56 loads.

First trip to the field proved this rifle’s worth. The 5.56mm grouping was tight at 50 yards, and the CCML handguard made mounting accessories easy. I appreciated how it came ready for California’s requirements without extra modifications.

Ran several boxes through it during a range session. Accuracy was excellent with Federal ammo, but it had a couple of failures to feed with cheaper steel-cased rounds. The handguard felt sturdy and the overall build quality met my expectations for the price.

I picked this up for range days and it handled beautifully. The CCML handguard stayed cool even after a few magazines, and the 5.56mm chambering was spot-on with the ammo I used. Having a rifle that meets California regulations without sacrificing quality made the purchase worthwhile.

After breaking it in at the range, I found the ergonomics comfortable for extended sessions. The handguard texture provided a secure grip, and I had no malfunctions with brass-cased ammo. For someone in California looking for a reliable semi-auto, this is a solid choice.

Used it in a practical shooting event and it performed without a hitch. The 5.56mm recoil was manageable, allowing quick target transitions. Having a rifle that complies with state laws while delivering solid performance made me glad I chose this model from Cal Guns Depot.
