Been searching on here and I have more questions than answers. I have a AR15 in .223 VLTOR upper / lower with a 20" white oak barrel and I am looking to upgrade the handguard from a quad pic rail to Mlok. Looking for something in the 15-18" length range in FDE. I want something solid but not too heavy (not lightweight). Pic top rail is needed. I would prefer 18" to put the bipod further out. main use of the rifle will be precision plinking (not competition) and hog / bobcat / coyote control with shooting ranges up to 400 yards. I consider this a semi precision rifle with under 1 moa accuracy. Ideally the handguard should be under $200 but will spend more for the right one.
