Home Forums Hunting & Shooting AR and Tactical Rifles First Pistol Assembly

I am gathering parts for my first AR pistol assembly (build).

Currently have:
PSA stripped lower
KAK LPK
BA 10.5" 556 Nato barrel (on the way)

Need to get:
Upper either built or will need bolt assist and E-port cover
BCG
Buffer assembly/Stabilizer (thinking Shockwave Blade)
Gas block and tube
Muzzle Device
Handguard
Sights

Help me out Fire Tier 1 Operators!
What am I missing?
Any pitfalls to avoid?

Thanks

For a brace go with either a SB3 or a SBPDW. I have both but really prefer the SBPDW

If the PDW wasn't more expensive than a stamp, and with the whole month-ish turnaround on e-form 1 right now, if one were building a pistol to avoid NFA entanglements, the SBA3 is the route to go. The PDW is magnificent, and ideal for those in non-NFA friendly states. But if I were in the market for the SBPDW, I'd honestly probably just file a stamp and wait the month.
