White Oak Precision A4 Service Rifle uppers built with Bartlein cut-rifled blanks. 

This upper is available with three different Bartlein barrel choices.  1) Cut-rifled 4-Groove 1-7 twist;  2) 5R Rifling, 1-7 twist; 3) Bartlein's Transitional (Gain) Twist in 8-6.5.

White Oak Precision Service Rifle uppers are primarily designed for the new CMP rules which allow the use of optics in Service Rifle matches and are fitted with a railed .750 gas block to allow the use of a clamp on front sight. (A clamp on front sight that measures 1.395” from the top of the rail to base of the sight blade notch will give you an "F" height front sight.)

White Oak Precision uppers are offered with either traditional A2 handguards or a Geissele MK7 handguard for shooters who desire a full picantinny quad rail.

Uppers includes Black Nitride Finish Complete Bolt Carrier Group and a standard charging handle.

Both pre-ban and post-ban configurations are available.  All barrels have an 11-degree crown, pre-ban uppers are threaded 1/2 x 28 and have an A2 flash hider installed. 

Accepts our National Match Carry Handle (1rch4).

All White Oak Precision Service Rifle uppers are legal for CMP/NRA competition.
