What to do, what to do?

The BackUp Iron Sights showed up today.  So now I have the complete assembled lower, national match two-stage trigger, the 6-position stock and buffer assembly, the BUIS, and even the barrel hardware less the barrel left over from my last build.

What to build, what to build?

I really wanted to build a .45 carbine on the AR platform, but the lack of mags from the only manufacturer of complete uppers (Olympic Arms) is putting a severe cramp in that idea.  Remember I'm also limited by New Jersey's restriction on mag capacity...even if I went with a 9mm.

The same company makes 9mm carbines that use standard Glock mags, but you have to have their dedicated 'Glock lower'...and I've already got a Rock River standard lower for this build.  The two stage trigger would be no good for a pistol caliber carbine anyway and I'd have to buy a standard trigger kit.  I'm not much interested in building a 9mm anyway.

My son Jess' suggestion that I build a light CQB carbine is a good one.  The more I think about that the better it sounds.  The extra money I wouldn't need to spend could go toward an Eotech holosight.  It would sort of look like this one modeled by the wife of Heartless Libertarian (which I believe is a 9mm carbine upper on a standard lower).

Lots of guys are making 9mm, .40, and .45 carbines anyway...HK has the no longer imported USC ($1500+), Feather USA has 9mm and .45s ($750) that look like grease guns, Keltec has their strange looking Sub-2000 ($400) in 9mm or .40, and of course Beretta has the futuristic Storm ($800) in 9mm, .40, and .45 using standard Beretta mags.  I can't say I like the looks of them much...I preferred the out of production Marlin Camp Carbine in .45, but I could eventually go for a Beretta.

I guess I'll build a light CQB in 5.56 and get the Beretta in .45 down the road.

Thanx Jess.
