First AR build complete!

Well, here she is boys! Thanks for all the advice and help. Hux the M-4 website is an awesome source of info and BCM can't be beat!!!! Pros-Side bolt discharge handle vs the old t-handle charger on back of the receiver. Cons-YHM handguards are a little rough and may cause grip bite. I still need to purchase a few more specialty tools to making assembling an AR a little easier. Upgrades in the future. The trigger still has too much creep and travel in it and is not as crisp as I like, will probably fork out the $200 for a good drop in trigger assembly. Optics, yes, but I don't know what to put on it as I already have a Leupold Prismatic on my Stag Model 3. I will also build another 16" mid length upper in 5.56 with a 1:7 twist to shoot heavier bullets. I would like to put a gas piston upper on it as well. Will use BCM for the barrel, bolt carrier assembly, upper receiver, lower parts kit, etc. Will definetly go with smoother free float hand guards! Lower will be another Delaware Machinery if I could only get someone to come of his lower that has the next consecutive serial number to mine!!!! ;D You guys have been a very bad influence on me with this black rifle thing!!!!!! ;D It's starting to eat away at my bank account in a good way!!!!!
