What does everyone prefer for a 10.5" build? Im looking at the phase 5 kit, but I've seen many other assemblies I like the looks of too. There is one out there that has a "fluted" tube, who manufacturers that? Buffer weight reccomendations?

I have built two pistol lowers with a kit from Palmetto Armory. They have the fluted looking tube that you are asking about. I belive rock river is the manufacturer of that buffer tube. Seems like I paid about 79-89 for the complete lower kit. http://palmettostatearmory.com/index.php/ar-15-05/lower-parts/build-kits/psa-pistol-lower-build-kit.html

I used the spikes tactical Kit for mine. I chose it because it uses a castle nut. Joeboboutfitters.com has them for around $60 I believe.

What do most kits use instead of a castle nut

RR tubes dont need castle nut, put your end plate/sling loop on,some filing of the tab, then your good to go
IMO is the cleanest look for pistol tube

Exile makes a nice rubber or foam tube cover
I also like Paracord wrap

I have three AR Pistols
I prefer the Rock River tubes ( PSA tube is RR )


as far a buffer weight depends on caliber
my 556 with 7 1/2' barrel is H, 300 blackout 10 1/2" barrel is  H2, and my 9mm  7 1/2" barrel is spikes 9mm and spikes spacer
all of mine use standard carbine spring

So the unique features of each are:
Spikes- has an integrated QD socket at the end and uses a castle nut
Phase 5- has the foam cover as well as the castle nut
PSA- has the fluting and it's cheaper

Rock River makes the fluted tube. Highly recommend PK firearms for their total kit. Comes with tube, spring and buffer which you can upgrade to H2. Highly recommend the H2 weight upgrade!!!!!! PK is also a sight sponsor so you can find their banner above.
