Trying to build a pistol. Couple questions....
Upper?????? 7.5" 1/9 twist chrome lined H-BAR barrel, Yhm specter gas block, Yhm Diamond carbine quad rail, Yhm 5C2 Flash Hider, Magpul MBUS Flip Up Sights, and Mil-Spec upper with M-4 feedramps
LPK???? Looking to put a dpms lpk minus trigger group. Install Timney 667S AR-15 Small Pin 3lbs Solid Trigger in place of missing trigger group with KNS Precision Non-Rotating Trigger & Hammer Pins to hold it in place.
Buffer and Spring???? Looking to put Wolf XP Spring and BCM H-3 Buffer
BCG????? BCM Bolt Carrier Group (MPI) - Auto
Buffer tube????? LMT 6 position buffer tube, castle but, and end plate. WIll wrap HEAVY with para cord to prevent easy installment of butt stock.
Thanks, looking to SBR once done and if it all functions well get the paperwork sent out.
If you're going to build a collapsible stock SBR out of it later, use a carbine buffer tube, just don't put a stock on it. You can use any buffer tube you want for a pistol so long as it doesn't have a stock on it. I'm using a rifle stock length buffer tube on mine since the pistol's a legal placeholder.
If you have another carbine @ home, then no worries about an extra stock about. If this is your only AR, wait'll the paperwork comes back before ordering the stock, or stash it @ a buddy's house.

I'm sure someone else will chime in but I think you'd be better with a 1/7 twist in a 7.5 barrel
Id recommend a 1:7 barrel, as it will allow you to also accurately shoot heavier ammo if you'd ever desire to or be willing to spend the big bucks on 69+ grain ammo. Also, this is a personal preference, but id recommend spending the extra money on Troy sights. I'm a big fan of polymer, but when it comes to something as critical as sights, I prefer something more solid and rugged.
