I'm currently collecting the last few parts for my build and I'm becoming confused by the buffer/extension tube situation. They seem to range in price by a huge margin, and I'm wondering how important is a good buffer kit is vs any old buffer kit? Dealer inventory is also a factor in terms of what's actually available. So I ask you good people of CGN, what do you use/ recommend? and why?
 
Rifle or carbine?

A standard rifle buffer mated to a standard rifle length gas system is pretty idiot proof, almost anything will work.

The carbine gas systems are much more finicky, and not mating it to a proper buffer can affect functioning signficantly.

Forgive my ignorance, but I believe it's a carbine length. I have a complete Colt Canada 15.7" upper. There is of course the option to just fork out the cash for a complete CC lower, but I was hoping to assemble the lower myself.
 
A CC 15.7 upper should have a mid-length gas tube and will not be fussy with buffer weights. Better buffer tubes are smoother inside and tend not to have that annoying "twang" when the spring cycles on firing. That said, any buffer tube and mid-weight buffer will work.

Thanks for the info. Any recommendations on what's a better buffer tube?

Haven't sampled enough to really know but my DD buffer tube was quite better finished than my no-name. A few hundred rounds and lots of grease now has the no-name running just as well as quietly as the DD. I honestly do not think that spending more on a buffer tube is worthwhile. Save the money for a better trigger, optics, ambi-safety or BAD lever which can be more of an improvement.

No one runs a mid length gas system.

Is it IUR or SFW upper?
 
Colt are carbine length. Most bulletproof method, standard carbine buffer with an adjustable gas block, cheaper than buy all kinds of different buffers and not to worry about which buffer to run depending on what ammo.
 
There is nothing bulletproof about an adjustable gas block. Tuneable, user friendly? Sure.

Bulletproof would be a pinned gas block or FSB. Pretty much any buffer will work in a semi carbine system. It only becomes an issue with FA.

wrong
the cc 15.7 does not have a mid length system, it has a carbine system
