I have a 1x4 Norco scope on mine itsfiredabout 800 to 1000 round o far. I really like it.
It hates Remingtons, wildcat and standard velocity ammo (except S&B std works flawess).
I have used a bunch of different ammo in it.
American Eagle CPHP , worked fine 1 stovepipe or 2 on eject
Federal auto match , works great avg groups. This is great cheap ammo.
CCI , 32grhp and 40grRN ar tactical perfect best groups
Remington thunderbolt 40 eds, 3 rds suck in the chamber, fails to extract stovepipe s.. . Never again I won't miss what Remington became
Wildcat, dirty jams on feeding was not impressed by this. Won't buy again.
Federal powershok perfectly good groups
S&B standard, only shot 1 mag. Best group out of the gun and not one misfire or jam. Wish it was easier to get.
You must load your mag carefully. One of manage holds 24 but works best with 23rds and the others all 22rds. Load them one by one and tap the mag on your helmet or hard surface to seat them. Most jam issues are with loading the mags incorrectly. It takes a bit of practise and patience to load them well. Otherwise the gun is great and shoots very nice groupings at 100m for a semi. I am having fun with mine.
