    4" AC Nemesis Barrel on SAR12C Semi

    Posted by SNEAKY SNEK on 31st Jan 2021

    I love it. My setup is a Carmatech SAR12C Semi and at 40 yards, it's very accurate. I will continue to test its distance limits but I play aggressively so this will do great for most games. I have a bolt action SAR12C so I'll keep my semi SAR on a remote line as a sidearm for those sticky situations in big games.

    I've found DefCon Paintball to have it in stock before Carmatech did - it's still not on their website nor any other US site. Weird but oh well.
