The rifle turned out really nice, but the hardest part is trying to stop adding stuff to it. I ended up buying a rail to put on the handguard to attach a recently purchased bipod and soon to be purchased folding foregrip. I've also thrown on a 3 point sling and looking at a 3x9 scope. Did I mention this thing is darn heavy?
I've shot 100 rounds through the thing (worked very well) and realized that $40/100 rds. is gonna keep me from buying the next gun on my list. I've invested the money and time and taken up reloading since then, and I wish I would have saved my brass.

My next visit to the range will consist of me testing my various loads through the rifle making sure I'm not exceeding the rifle's limits.
Conclusion, build your own rifle if you have the time and confidence in yourself, and the same goes with reloading. If you follow the directions properly, the rifle will either go together or it won't. The best benefit (besides pride) in putting together your own rifle, is that you get to see first hand how every little piece matters and what to do when something fails.
