| I am building my first at, and looking at http://www.joeboboutfitters.com/mobile/default.aspx#P7497. What is a multi cal upper? I am looking to use this with my spikes lower. Am I going to run into issues? |

Any un-barreled upper can be considered "multi caliber". Have you considered going with a complete upper? The money spent on proper tooling could go towards the rifle itself. On the other hand, assembling the lower yourself only requires a couple basic tools and allows you to peice together some higher quality components with that money saved on the upper tooling.
Congrats on the build and welcome to the community. |

Try this one. http://www.spikestactical.com/upper-receiver-forged-m4-flat-top-multi-cal-p-123.html I have considered complete uppers, but it's easier to sneak a couple hundred dollars past the wife over a long period of time vs $500 + all at once. If you don't mind the chance of some small blemishes these BCM uppers are about $40 cheaper. I've used several on different builds and they have all been great. ETA: The Spikes should suit your needs just fine, just giving some other options. |
