Spike's Tactical Stripped Lower/Upper Set - Gray

I purchased the Spikes Tactical upper/lower in FDE.
Oden Works 416r barrel and Fail Zero BCG. Fit and finish very good! All components fit well. No modifications required to finish the rifle with standard lower parts kit. I use the Primary Arms fixed 5x optic on this rifle. I waited until barrel was broken in and I had around 500 rounds down range before writing review. No failures, no malfunctions, fully functional and very accurate rifle. I do not have a lead sled or anything like it, but shooting off my ruck with a rear bag produced groups just a shade under 1 moa. I do not use steel ammo but shoot federal 55g or m855. Not great ammo but this rifle delivers the best accuracy possible with the ammo I feed it. This is a work rifle and it does not have an easy life. Next build will be the same but will use the Primary Arms 1x8 for a touch more magnification. These scopes are plenty tough for work and really make ranging and accurate shots easy. Best you can get.

This receiver set looks great and has no play between the upper and lower. It seems as though it is duracoat not cerakote and therefore fills in the gaps between the upper and lower. The main drawback and reason for 3 stars is because I had to pay a gunsmith $100 to grind off the duracoat from the threads so that the barrel nut would actually go on. You also cannot take it down without using something to push the takedown pins out and something to pound it back in because of the coating. Now that it is finished the build looks great and functions fine but if I had to do it again I would buy an upper and lower receiver set without the duracoat and pay $100 to have it cerakoted properly.
