In regards to the handguards I would think you might have been happier with a true free-floated handguard/tube, and with the grip that depends on your personal taste, I like the A2 style but some love the CavArms grip.
Well, I am very impressed with the Hogue O.M. series, monogrip and aluminum free float forend tube kit for the AR15. The tube required a little gunsmithing, but is well worth the money. The pistol grip is with out a doubt the best I have ever used. I can recommend this product. Best part is made in the :usa: for the :ar15: Singleside out.
