I guess I want to piece together a carbine----16" bbl free float BUIS 6 pos lower etc---whole cqb deal---must be reliable and accurate----would I be better off just buying a factory gun, or should I build my own---if so which factory gun, or where to start building my own?----This will be my home defense gun, so must gobang when I pull the trigger---figure if they can get past my pits ---I need a good gun---thanks in advance all

I built my own out of Bushy and RRA parts plus a Daniels Deffense free float handguard and threw an ACOG on top in an ARMs mount I havent had a problem with it after the initial break in

Quoted: Just a thought... Freefloat rails are of little benefit in a CQB role. What you really want is a railed forend for mounting ninja stuff. There are good two piece handguards out there that may serve you well at a lower cost than a free floating system. Having said that, you can't go wrong with a Daniel Defense or LaRue either...

I couldnt find an Arms mount for a ninjitsu sword

tat2u - contact me asap, please.

I built this "Blaster" for just under $400.........Alot of GI parts.......NO FTE, NO FTF  I zero it like I would at "Range fire" all 3rds were touching at 25meters.

You might try a site search for "recce", that's one variant of what you are describing, and you'll probably find other pics to give you some ideas.  One big question, are you looking for an iron sight rifle or are you going with optics?  Many of the builds you see now are geared for optics, but if you are going to shoot iron sights then you can go a lot simpler.  BTW, midlength gas system has a lot of advantages for a 16" barrel, personally I wouldn't buy a 16" barrel with a carbine length gas system ever again.  You might also take a look at the midlength photo thread for ideas.
