Scooer22, Correct, on the marlin it would be a buffer tube in name only. Loonwulf, that’s the one I’m looking at. Good call on the second link, sadly it did not occur to me to look that one up lol. Of course the idea came to me as I was getting ready to purchase the folding variant, midway didn’t know and choate was closed today. I’ll try them on Monday I suppose, but I would imagine it would be the milspec now that I’ve seen your second link. I appreciate it! I’ll try to update if I can get a hold of choate. I like the “old school” flair of the folder, but I’m thinking that the LOP may be longer than factory wood is, plus I may be able to gain some versatility with the adjustable, assuming I can install a stock I like. Kind of a blend of old school PCC with newer furniture. I would truthfully rather just keep the wood on it but it would appear finding a replacement should it ever split (I’ve ordered the 21 spring and buffer) is near impossible, so I’ll save the original for the next generation.
