Range Day shooting Pistol Caliber Carbines - Juggernaut Tactical 9mm

Range day with my buddy shooting our pistol caliber carbines. Neither of us have shot a competition before with rifles so we spent the day getting used to aquiring the first target from low ready.
My rifle is a Juggernaut tactical 80% build
It uses a faxon firearms 16" barrel
Forward controls design ambi safety
Holosun AEMS green dot optic
Scalarworks leap 11 riser
Timney competition trigger
My buddy is shooting a recent build from a 5d tactical lower, cmmg lower parts kit and a Davidson defense complete upper with a 16" barrel.
Both builds ran flawlessly all day using 115gr brass. I previously had some issues running 124gr sellier & bellot brass, but the rifle feels broken in now with around 1000rds through it!
I'll be using the rifle for steel challenge events this year!
