Fit and Finish is better than great! Matches up to my spikes lower (purchased through a different vendor) better than if I'd bought a matching set from someone else.

Absolutely remarkable M4 flat top upper receiver! The anodized finish is perfect, T-markings are clean and clear, and the Spike's logo tops it off showing you mean business. Hands down, this upper receiver is a wise investment for anyone starting their new build. At this price and quality its a guaranteed steal! Received my new Spike's M4 flat top upper on 2-15-2010...2 thumbs up, way up!

I bought one of these and built an awesome 16"Tactical with it. Fit and finish is excelent. M4 ramps matched perfect with the barrel. The BCG was also from Spikes and I get nothing but compliments on how it looks as well as how accurate this piece is. Never a jamb or misfire. I have 3 or 4 people who want me to duplicate my rifle for them.
