In general, up until Covid-ish (coincidentally, I think?), I would build or buy anything I wanted, at least temporarily, and at least for anything which wasn't super-expensive based on non-performance characteristics. Multiple times in my life, that philosophy DID mean I'd find myself looking at a grossly bloated collection - or rather accumulation - of firearms in my safes which I just didn't REALLY love, or REALLY have validating use to own (NOT saying anyone needs any more excuse than "I want it," to justify owning any firearm, but for my personal calculus, I wanted other things more than I wanted 300 different firearms which I never really touched - I prefer to make use of mine).
Admittedly, although not a rifle but a shotgun, I've lusted after a race built Benelli M4 for a long time - and I want to go through all of the hoops to modify it to supplant an M2 as a 3 gun race shotgun. I just haven't been able to bring myself to do it. I've bought 2x M4's, and I did have an M1S90 for a while, but I can't quite bring myself to put the work and money into the M4 to get what I want. Yes, I know guys are using the M2's, yes, that road is well known, but I like the M4's, and I really want to build up an "M4S90" type 3-gun competition shotgun someday. I also would REALLY like someone to convince me to buy another M1A "Socom" or whatever they're calling the 16" model today, and I've always wanted to have a Garand "Tanker" sitting around to look at, but in 2024 and beyond, I think those ships have sailed, docked, and been dismantled to build homes in the New World, and won't be returning to my port... I suppose my more tangible bucket list right now is looking at trying to modify a Marlin 1894 to accept a little longer cartridge (might have to go to a Marlin 1895 action length, smarter to use an M92 action, however) to feed my 357/44 B&D Mag cartridge loaded with Speer 180grn HotCor rifle bullets... I just can't quite get the ball rolling on that project - it's silly, but I really like the idea, and think I can get it done, all in, for around $3000, so well within reach. Probably becoming very tangible, but something I've waited a very long time to buy, I've always wanted a NICE, not extravagant O/U trap gun. My son is starting into the sport for his school team, so he'll get a decent option, not quite sure if we're going with a B gun yet, but leaning heavily towards a B gun clone to keep the price in reach that he might get an O/U and an Unsingle, and I might get an O/U to match his so we can keep practices more competitive as he learns the sport. But I suppose that's another shotgun... I'm still parlaying a proper 22LR for NRL22/PRS Rimfire, but I've started that project now by selling a few other firearms to begin funding that build - after the PRS Finale this season, I have refocused that I really want a 22LR practice analogy which perfectly matches my primary centerfire rifle - that has been ~8yrs coming, and still not realized, but I'm hoping I can convince myself to finish it this winter/spring.
