My budget is so screwed... First step done. Looking at KAK valueline barrels, https://www.kakindustry.com/ar-15-p.../contract-458-16-inch-carbine-melonite-barrel Looks like they have a bolt for around $90 as well. Gonna mill out the ejection port on an upper myself to save a few bucks, and I already have an Odinworks tuneable gas block for it. I may go with a dissipator look with a magpul rifle forend, but not decided yet. What I really can't decide is weather to build a carbine upper or a pistol length upper for my SBR lower with this barrel, https://www.kakindustry.com/ar-15-p...ls/contract-458-8-inch-pistol-melonite-barrel So, feedback anyone?
