Fiocchi, this is good target ammo. I use this alot and groups super well on my Noveske Afghan gen 1 upper and a Noveske Gen 2 lower...Supressed!!!! Yeah on a YHM thread on Phantom 5.56 Can with a Vltor A5h0 buffer? Yeah the lightest one they got and the m16 recoil spring with a Young N/m ar15 bolt carrier group so mine is on point! fiocchi! Yeah that is on point too! I shot 80 rounds suppressed and the Noveske probably could have gone more but why? Now, if it was unsuppressed probably 240 plus rounds and both the ammo and gun will keep going till the cows come home. Stack 'em deep while they are cheap! Patterns prefect too and easy to clean.
