I’ll have to take it apart and take a look. I do plan on replacing the stock after a little range time. I’ve read that the SPS stocks like to flex. Not sure what I’ll replace the stock with yet. If your stock is greenish, and the barrel is threaded w/ 1:10" twist, you got the AAC-SD. I can almost guarantee Redfield isn’t FFP. While it’ll be fine for what you’re doing now, if you plan on doing it regularly, competing, or shooting unknown distances a FFP scope would be ideal. Easiest way to tell if yours is FFP is look through it while zooming in and out. If the reticle doesn’t change scale, then it’s SFP (second focal plane). Also note that FFP/SFP doesn’t matter on fixed power scopes. FFP allows you to calculate distance at any zoom length if you know the size of the target itself. With SFP, your calculations will only be correct at one single zoom level. Our military uses Leupold SFP scopes on virtually every sniper rifle that’s not used by SF, Seals, etc… Once you get the hang of things, invest in a FFP scope with mil/mil turrets/reticle. If both the reticle and the turretss for windage and elevation are in milliradians, it also makes things a ton easier and faster. Most of the military uses mil-dot reticles with MOA turrets. While it still works fine, somewhere along the process of calculations distance or wind speed they have to convert mils to MOA so they can adjust accordingly. For stocks, just about anything that’s not rubberized plastic will be better. It all depends on your budget. Don’t be afraid to go overboard, because usually you pay for what you get. I have an Accuracy International AICS 1.5 which is pretty perfect. It takes very durable and reliable detachable box mags, has adjustable check weld and length of pull, mounting point for a Harris bipod or their own bipod made by VersaPod which clicks in and out of the front of the stock in one second. Your old stock and bottom metal will prolly sell for around $75-90. --- _[View the full topic](https://forums.speedlife.net/t/the-official-gun-thread/242496)._
