I fired my new rifle today, a .223AI in a McMillan HTG. My other rifles both have A5 stocks with thumb wheel adjustable cheek rests and I had a difficult time getting a consistent cheek weld on the HTG using an Eagle stock pack and padding/spacers under it. I don't recall ever seeing one and was wondering if anyone has a HTG with a saddle cheek rest installed by McMillan? I know I can buy one from Karsten, I've had one before and they're great, but that voids the warranty and I don't want to do that if I can avoid it.
