I have about 5k rounds thru mine (HK MP5 SD)......I have a 4 reticle reflex sight on it zeroed to 25 yards......I love plinking with it and am good just shooting from the hip.........Everybody at the range can't believe it is just a 22.
My buddy has one and, NO specific ammo is required, it will shoot just about anything.
Now, he and I only shoot standard 22LR's. No subsonic/quiet or hypersonic ammo.
But, I think as long as you stay away from subsonic/quiet ammo you'll be fine.
once the shortages are over with you can then decide which it likes best
Just bought mine on Saturday 500 rounds so far no problems I love it just ordered 2 extra mags and I am looking at optics now also mine will even shoot the bulk 36 grain even though the salesperson said it wouldn't
