10.5" Upper Build Question

[nastee]

Should we go with a carbine length or pistol length gas tube?

10.5" barrel
10" seekins rail
Ferfrans CRD muzzle
Stripped upper
Rainier Arms Raptor charging handle
AIM NIB BCG

Any advice is appreciated.

Thanks.

buy the one that fits your barrel...

I've got Carbine on my 10.5", cycles fine with a KX3 on the end and a Spike's ST-T2 buffer, but it'd probably cycle fine without the can and a standard carbine buffer.

I don't know if the buffer tubes are of different lengths, but I'm using a KAK Industries buffer tube, so I have the ability to adjust the LOP, not sure if you can do that with a 6-position buffer tube.
