You’re asking the right question, man. When you're stuck to $250, you gotta focus on things that affect the interface between you and the rifle, that's where you get the most bang for your buck. Forget the fancy stocks unless you can snag a used one. My biggest tight-budget win was always the trigger...for around $100-$150, you can usually drop in a fantastic trigger like an ALG ACT or a good single-stage from Rise Armament. A crisp, light trigger instantly makes the rifle feel custom. If you have any cash left, grab a better grip, like a Magpul K2 or BCM Gunfighter, to improve control.
