Ordered 4 as most all my rifles are 18” barrels. Received all four and introduced them to their new mate. Excellent buy. Thanks to the OP for posting this for everyone.
I’ve got my rifle measured at 39” from snoot to boot. I believe it’s 18” plus the little Bastard. I had just enough foam buffer on either side to feel comfortable. Worth mentioning because the wheels are recessed I had to place the barrel between them because the stock wouldn’t fit. It works out because you want to load it heavy side towards the wheels but it’s worth mentioning.
