Some assembly required

[Bike Effects]

I have been trying to score an OPS-4 upper receiver for six months and have now given up. I'm ready to build my Grendel upper, v 2.0. I will build with the parts shown below:

[ATTACH=CONFIG]3863[/ATTACH]

• · JP Rifles CTR-02 Billet upper receiver with removable brass deflector
  
• · JP Rifles JPBC-3 Stainless Low Mass Bolt Carrier with QPQ Black Hard Coat.
  
• · JP Rifles JPGS-8 Low Profile Adjustable Gas System. (.936” bore)
  
• · Krieger 22” Cut Rifled barrel with rifle length gas system. (.093" Gas Port)
  
• · White Oak Armament Varmint Rifle Float Tube. Comes with a barrel nut that the gas tube passes over, not through, for precise setting of torque on barrel nut.
  
• · BCM Gunfighter Mod 4 Charging Handle. Machined from 7075 TJ Billet Aluminum and hard coat anodized.
  
• · Burris AR-P.E.P.R. Extended Scope Mount.
  

• · Leupold VX-2 6-18X40mm adjustable objective Target Scope with Fine Duplex reticle.
  

I will use my .223 lower with MagPul PRS stock, JP Silent Captured buffer spring and Timney Drop in Trigger.

I will have one more delay as I had to send the receiver back to JP and have them cut M4 feed ramps.
