WCChapin | 6.8 SPC – Will it Run? | The 16″ Upper on Rifle and Carbine Lowers

The second range visit with the recently assembled 6.8 Remington SPC upper receiver – running with both carbine and rifle lower receiver setups.

The test ammunition was Hornady Varmint Express 110 Grain V-MAX (2,550 FPS) and Hornady Custom 120 Grain SST (2460 FPS) – both ran well.

I also removed the inexpensive rear sight and installed a Luth-AR branded carry handle.
