Best "sleeper" you ever bought?

I actually just shot one of them today. Cugir m69 made in 1975. Was stacking sk subs at 50 with 50 dollar 4x truglo piece of garbage. The mil dots were covering the 2 inch dot. I'm thinking I have 100.00 in the old rifle. Another would be a norinco jw15 definitely a shooter. Have old tasco 3-9 silver pronghorn on it. Don't think I paid anything for it might have come on some random trade or something. Might have 100.00 or so in it. They are fun. Really really enjoy shooting them especially when someone has a "better"rig and after awhile they can't help but ask "what kind of rifle is that?" because of the way it is shooting compared to what they have invested big money in. Rude I know, cheap thrills....

Marlin model 60W in excellent condition I bought off a guy for $100 last year. It continues to tear the same hole over and over at 50 yards and can hit 1/4 moa at 100 yards in the right conditions. At my outdoor range, I tend to hit around 3/4 to 1 moa with better groups on occasion. These are all 3 shot groups. Can't make this stuff up! Best $100 I've ever spent. It recently became my new squirrel gun due to it's insane accuracy and cheap price tag. Typing this still has me in disbelief.

Here she is! Mounted a spare Trijicon Credo 3-9 I had laying around. Makes for an excellent hunting scope. The scope was over 5x the cost of the rifle 🤣.

Brno Model 4 built in 1957 with cheap scope, $ 400.00 at my Lgs. I bought it last year because It was as close as I could come to a cz at the time. It shoots groups as well as my buddy's vudoo. Total dumb luck

My best "sleeper" was actually given to me by a local gun shop owner some 25 years ago. The story starts when I stopped in the shop to pick up a 45 ACP pistol I had on layaway. As I'm doing the paperwork, the owner handed me a filthy 22 rifle. It was not only covered in 20 years of dust but was missing the mag and had been spray painted black (entirely) at one point in it's sad life. .He had apparently taken it in as part of an estate and didn't want to bother to find a mag and clean it up. The deal was, there was no charge for the rifle . He just wanted to transfer it into my name to be rid of it from his books (and tiny overflowing shop). He knew I was a sucker for old 22's as I had often bought old .22;s , (mostly Mossbergs and Marlins,) as refurbishment projects. "Take it, it's yours" he said.....This guy was notoriously cheap and the fact that he was giving me the gun, had my antennas up! I refused at first as this thing was FAR uglier than anything I had attempted to save in the past. Still, he persisted and when I finally scraped some paint off the barrel, I saw that it was able to read" Scoremaster"...scrape, scrape, "Remington 511..", I eventually gave in mostly just to shut him up. I figured worse case, I could make it a parts gun or tomato plant stake.

Forty Five minutes later I was just finishing test firing my new SW 45 acp at my gun club and found a few 22's rolling around in the pocket of my range bag. Hmm, I figured, "Why not try the old relic?". So I grabbed the rifle out of the truck, cycled the (CRUNCHY ) bolt and tried the trigger. It seemed to work..... From there I blew down the barrel a few times to assure it wasn't plugged. The bore was filthy but it was clear. Here goes! So I stuffed a single 22 round directly into the chamber , looked down the rattle canned barrel and iron sights and took a bead on a chunk of clay pigeon in the 50 yd berm and squeezed..... Well to my amazement : a) the rifle actually fired an b) the clay pigeon shattered! Hmm, I thought. Must me a fluke. Trigger wasn't bad though"... so I stuffed another round into the chamber and lined up on a 1/4 chunk of the remaining pigeon. Again, the rifle barked and the target shattered. Well for the next 10 min I was scrounging through the bag finding stray 22 rounds and eagerly shooting golf ball sized pieces of orange clay at 50 yds and getting similar results. I honestly couldn't remember shooting an iron sighted .22 that well in a ling time!
Fast forward another 2 hours and the 45 was already forgotten in the safe while I lovingly began stripping and disassembling the rifle. Two days later, it emerged from my shop completely refinished in true oil with a cold blue. 3 days after that the mag I found on ebay showed and she was complete! Anyway, that "throwaway" rifle shot lights out every time it left the safe. I kept it till just last year and then passed it on to someone with a kid.
