AR 15 Upper Options

Thread starter #1
The thread about youth calibers got me thinking about complete upper options for my ar 15. From what I have found online there is type 1 and type 2 for both the 6.5 grendel and the 6.8 spc. Is the factory ammo offerings made for type 1 only? And type 2 must be hand loaded for? Sounds like either caliber is great for deer out to 400 yards with not much difference one way or the other. Any suggestions on complete upper brand for either. I would be looking for something that shoots factory loads. Thanks for input!

6.5 GRENDEL: TYPE I VS. TYPE II

I get a lot of questions by clients on difference between 6.5 Grendel Type I and Type II, so I've decided to jot down major points. The difference is in head spacing!

The original Grendel, and what we now call Type II 6.5 Grendel, was designed to be used with a Grendle bolt, or.136 head spacing.

The patent was never released and to avoid any legal litigations, Les Baer Custom had adjusted 6.5 Grendel design of the barrel to make it .125 head spacing. We are now call it Type I Grendel. LBC has .295 diameter neck while Grendel has .300 diameter neck.LBC has a straight taper in the throat while Grendel has a compound taper.

The beauty is, LBC designed the .264 LBC cartridge to be completely compatible with a 6.5 Grendel. It also take 7.62x39 standard bolt, which in the long run gives a clinet greater flexibility to interchange their barrels on AR-15 platformwhile keeping the costs down.

Hope it answers some questions on a basic level. You decide which type of Grendel is right for you!
