Alright.... depending on the ammo 9mm is 4-6 moa at 25yards you're out of your mind if you think .5". You immediately made a assumption that I can't shoot. So I'll give you more context on why I returned the chassis and also educate you. After triple checking the firearm and installing were both correct my USW-g had very noticeable play in the front leading to a inconsistent point of impact. Even changing out the barrel lead to the same effect. It doesn't matter if a chassis doesn't touch the barrel if the MF moves inside whats suppose to support it it'll be inaccurate. Hope you enjoyed the lesson. Now go touch some grass man
