Hello; So I have 1,300 for a new upper, and wanted to know from which mfg to buy from; I'm torn between the LaRue Stealth, Noveske N4, or the Newer BMC SPR Mk12. I'm looking for a 18" accurate rifle, that is also shtf reliable. I'm going to outfit this system with a NF 1x4 scope. thanks hardeyes Wanna kill these ads? We can help!
