Possible Ar-15 Build 9mm

[.45colt]

I have owned an AR-15 in 5.56 for many years but never tried to build one. Lately, I am thinking about starting a project to build one in 9mm since the long winter is coming. At the moment I am considering a Stag lower.

Are the 9mm parts more costly?

Any advice is welcome.

9mm is expensive

barrel will be hard to find bolt even harder not too many 9mm's in canada as compared to .223/5.56 cal

questar has some 9mm rifles and parts (or can get parts)

not that hard to build just hard to get parts
