This is a great gun by Sig Sauer. It looks & feels high quality. Fit & finish, great. Trigger & recoil impulse, great. Muzzle brake is surprisingly effective. I've enjoyed shooting with it, & training with it. The one & only warning I tell people about this gun, & all the Tread series, is the proprietary hand guards. They're so thin & close to the gas block, you realistically can't attach anything M-Lok by the very front end. I tried… a lot. I mean it's good quality. It feels good. But if attachments are your thing, it might not be for you, or you may consider a replacement hand guard. Me, I installed a front sight further back to prevent pressing on the gas block. Still 4 out of 5 stars for me.
