I have talked to sales people at Rock River Arms, Stag Arms and DPMS and all three are telling me that the popular rifles are out as far as eight months due to shortage of parts, especially barrels. I don't believe it is a volume problem as much as s supply shortage. Some people have stripped lowers and LPK's available with less than a month wait but even that changes by the month.
i guess i assumed that since prices were falling so fast the supply problem was cought up or close to. i know in febuary/march you couldn't find enough parts (especially uppers) in the classifieds here to build a ar and now you can build quite a few with the parts listed. but to be honest i dont pay alot of attention to ar parts anymore so i could be wrong
