I am a big fan of the 6.5 Grendel. A round doesn't have to go super fast if the ballistic coefficient is high. Harbour Arms is the first to offer precision snap caps in 6.5 Grendel.
Another first, Harbour Arms is now offering 6.5 Grendel Bore guides for AR15's. This bore guide is another item made by Boretech. Look for them in February 2019 on this website.
The 6.5 Grendel started life as a proprietary cartridge. The Grendel was designed by Bill Alexander to replace the .223 cartridge in military rifles.
This cartridge is a spin off of the 6PPC but was designed to handle heavier bullets. Most of the 6.5mm bullets have a better ballistic coefficient than any of the .223 bullets. This made the 6.5 Grendel much more efficient at 600 yards. The Grendel is tailored to fit in an AR-15 platform Modern Sporting Rifle at standard magazine lengths.
The 6.5 LBC was developed by Les Baer to replicate the 6.5 Grendel before it became a SAAMI spec'ed cartridge.
Our 6.5 AR fits both! Once again, Harbour Arms was the first to bring you the 6.5 Grendel snap cap.
6.5 AR (6.5 Grendel)
The 6.5 AR is Harbour Arms answer to your requests for a 6.5 LBC or the 6.5 Grendel. Our 6.5 AR fits both!
This cartridge is a spin off of the 6PPC but was designed to handle heavier bullets. Most of the 6.5mm bullets have a better ballistic coefficient than any of the .223 bullets. The 6.5 LBC or Grendel are tailored to fit in an AR-15 Platform Rifle at standard magazine lengths. This cartridge is certainly one that could replace the .223 in the AR platform battle rifle.
