"Pre-Fit" isn't the best for LR. And from my perspective, by a Hart and have it 'custom fit' and chambered to your action. LR and "drop-in" shouldn't even be in the same sentence.
We'll have to aggree to disagree, then . Pre-fit 'll never be anything but second best! The good chit ain't cheap.
Don't waste your time with Email. Its a 1 man operation and he gets a million emails. Call him during CST business hours (MN) and he will get you straightened out right away. He was due to get in a delivery about now. He basically guesses what is selling well and places orders and gets in 10-20 a time in popular calibers.
