Spike's 8.1 upper
This upper is well worth the price tag. Optics has lowest price anywhere! I went to range to test it out and it shot flawlessly and surprisingly not as loud or harsh as I thought for a short pistol upper.

High Quality Product at a Great Deal
I was on the fence about ordering this upper. Optics planet was running a great deal so I jumped on it. Excellent fit and finish, and cycles smoothly. I’ve been a Spikes Tactical fan for a while, this latest Upper just keeps me wanting more.
