White Oak A4 Service Rifle Upper configured for use with Optics and featuring a stainless steel Shilen ratchet rifled 1-8 twist barrel.
Shilen is a leader in button rifled barrels. We have offered their barrels on a limited basis for many years and have been very pleased with Shilen’s quality and service. We are now offering uppers featuring ratchet rifled barrels. Shilen's ratchet-rifled barrels have gained a reputation for accuracy, ease of cleaning, and many feel an ability to shoot through conditions better than conventional rifled barrels.
This model eliminates the front sight bases and replaces it with a railed 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.
Accepts our National Match Carry Handle (1rch4).
