Avoid this manufacturer - Sharps Bros. AR-15 Billet Stripped Upper Receiver w/Forward Assist

Avoid this manufacturer. This upper receiver has so much slop even while using a Sharps Bros. lower receiver. Purchased this and a Sharps lower and the fit is horrible. Contacted the manufacturer and all they did was respond with snide remarks on their email. Will never purchase another Sharps Bros product again. Instead of offering help they give smart remarks. You have been warned. Avoid this product unless you want to use shims to make it slightly normal. This is the loosest set I have ever built on. Avoid!!!!
