I'm in need of opinions please.

I was setting up to do a frankin A2 build, Got most the parts minus a bcg & charging handle. I like fixed carry handles & iron sights. Now the girls ain't big enough yet to manage a A2 stock, so I was gonna use an extra M4 stock so the girls could step up from their carbines. So here's my issue. I ordered a WW A2 Government Profile 20in Barrel Kit that I was going to use on a FN A2 upper that I've bounced around a lot lately. But today the BRD gods smiled on me & produced an unexpected stripped M4 upper receiver. I'm not sure what to do now. Sick to the original plan, or do an A4 so the girls can get started learning to work with glass as well. Most likely a Nikon Prostaff.

I'm in a quandary here. Would like to get some opinions. The girls are both 10 by the way.

Thank you
Matthew

do two black guns

Of that there is no doubt. I cant decide on doing one traditional A2 rifle & a M4gery, or an A4 & leaving the other as a A2 carbine.

I'm kind of confused about what you were saying, but here is what I think.

Use that new upper, build a little carbine to teach the girls with and also build that A2 rifle you want.
