75-200 USD
In NEW condition it's worth about $300 (it's not a good seller)...
Well, isn't that a happy little question! You can find parts for your 5mm Remington 592m bolt action rifle at your local gun shop or online retailers that specialize in gun parts. Just remember, it's all about enjoying the process of fixing up your rifle and bringing it back to its full potential. Happy hunting for those parts, my friend!
Remington's web site has a model history section. Ammunition hard to find so value not that great. Maybe 100 or so USD
Two models were made in 5mm caliber. The Model 591 has a 5-shot detachable magazine. The Model 592 has a tubular style magazine under the barrel. These guns were made from 1970 until 1974 only. Ammunition is no longer made for the Remington .20 caliber (5mm) rimfire. Original ammo, if you can find any, is going for around $50.00 plus, for a box of 50. Value for either model will vary upon condition. If you have one in 100% condition it may fetch around $150-$175.
Try Old Western Scrounger.
I paid $100 for one and plan to rebarrel it. Hard to sell with the cost of ammo for them. Just produced some ammo so value is helped. I want another for the action.
Try eBay or gunbroker.com
