Real-World Testing: Putting Luth-AR 20 in Bull Rifle Kit Minus Lower Receiver w/Coll. Stock to the Test
First Use Experience
I tested the Luth-AR 20 in Bull Rifle Kit Minus Lower Receiver w/Coll. Stock at my local shooting range, mounted on a lower receiver I had already assembled with a Geissele SSA-E trigger. The weather was clear and mild, around 70 degrees Fahrenheit. After a quick function check, I began zeroing the rifle at 100 yards using a Vortex Viper PST Gen II scope.
The rifle performed flawlessly right out of the gate. The heavy bull barrel helped dampen recoil, making it easy to stay on target for follow-up shots. I was initially surprised by how smooth the action felt, considering it was a brand-new assembly.

Compared to my previous AR builds using budget-grade components, the Luth-AR kit is a significant upgrade in terms of accuracy and reliability. It consistently delivers sub-MOA groups with match-grade ammunition, outperforming my expectations. The free-float handguard also contributed to better accuracy.
