And all I have done is bore sight it. I bought 500 rd for it . The only reason I bought it was because Hillary didn’t want me to have it. I really just don’t need it. Got a 30.06 and a 30.30 & a 9MM rifle . Now I just looked it has doubled in price. Thought it might come in handy (Just in case)
Suggest you clean it
thoroughly lube it properly, sight it in for a useful distance, re-clean/re-lube, then consider buying some high-quality magazines before those are tough to find--as perhaps banned.
Shooting your firearm in order to properly sight it in, and to test various brands of ammo will likely reveal any faults, and allow possible return to Ruger for service in the unlikely event such service is needed. Strongly suggest NOT making any irreversible mods to your rifle because Ruger takes a very dim view of user-made modifications, and if a trip back to Ruger proves necessary, return the firearm to original state before doing so.
Find some decent way to carry a useful number of mags on your person so that they are easily accessible--your pockets are not a "decent" way to carry mags. Magazines are considered "expendable" items by the Mil, as some inevitably get lost and/or damaged. Suggest you buy more mags than you think you will need in order to have spares. Suggest you consult appropriate sub-forums on ar15.com for info on magazines and ways to carry them.
Consider a decent "quick-adjust" 2-point sling and learn how to use it. Blue Force Gear offers the Vickers sling, and other companies offer similar products. This video will give you some excellent sling info:
If your rifle will accept a bayonet, consider obtaining one. While most will not be making any bayonet charges, most bayonets make for decent field knives. Typical M-7 bayonet and M-10 scabbard ensemble ought not be terribly expensive. M-10 scabbard can be mounted on most belts and on MOLLE/PALS surfaces by using a MOLLE "K-Bar" adaptor, available for cheap.
500 rds of ammo is what many users would consider a "good beginniing". Suggest you try out different brands of ammo, and stock up on those which seem to be the most accurate.
Strongly suggest storing ammo in airtight .50 cal ammo cans, along with a little "can" (kinda the size of a pack of cigarettes) of dessicant. Wal Mart has them online.
As you discovered, most decently-made firearms can be a pretty good investment. Some are not. As with decently made firearms, it mostly depends on condition and scarcity.
All best wishes!
