F4 Night Hawk – Ultralight Small Frame AR10


Common Use:  Hunting & Precision Shooting

* SUB 1/2 MOA Guarantee *

The F4 NightHawk is the latest release from a dominate line of Small Frame AR10’s.  F4 already had the lightest AR10 rifle on the market and we’ve now beat that by almost a full pound!

Not only does the Night Hawk dominate in the weight department, but we GUARANTEE 1/2 MOA accuracy (Bartlein Match Grade Barrels).  While ultra lightweight, the F4 NightHawk shoots very smooth with minimal recoil due to the hydraulic buffer system and Small Frame AR10 geometry and lower bore axis.

The F4 NightHawk is offered in the following calibers:  308 Winchester – 6.5 Creedmoor – 6mm Creedmoor – 6.5×47 Lapua – 22 Creedmoor – 243 Win – 260 Rem

The SF-10 is a compact, lighter, and more dynamic version of the AR10.

** There will be a $1000 cancellation charge for all SF-10 orders.  We do our best to build and deliver our rifles within the estimated lead times but due to the current climate that is not always possible.

When ordering, please let us know in the order notes section while checking out, your preference for the following barrel specs:

  • Barrel Length
  • Twist Rate  ** All of our barrels are now gain twist **
  • Gas Length

Current Lead Time:  20-24 weeks
