Wow, glad to see that AA released the Grendel. I had tried to have a 28" cut rifled barrel made but this was about the time that Saturn went out of the Grendel business and no one else produced them. I had talked to AA and had no luck with any of their suggestions. I ended up talking to Pacific Tool and had to order a 264 LBC AR reamer and go gage since they could not sell me a Grendel reamer then sending this to Krieger to have them cut the chamber. The funny thing is after I got the gun together and fired it and measured the brass the neck was .300. I was under the understanding that the neck should be .295 for that reamer. I then measured the reamer and sure enough the reamer measured .300. So now do I have a 264 LBC AR with a .300 neck or do I have a Grendel reamer that is marked as 264 LBC AR?
