Good buy!!!! - Adams Arms FGAA09004 P-Series M-Lok Rail AR-15 Rifle 6061-T6 Aluminum Black 15.5

These hand-guards are easy to install and REALLY dress up your AR. Lite weight, yet rugged, I hope to get years of shooting out of them. Just be aware that the included barrel nut requires a 1 1/4" wrench to install. This is far larger than most wrench sets. As I didn't want to risk damaging the nut by trying to use an adjustable crescent wrench, I ended up buying a wrench set (thank goodness for Harbor Freight) just to get the largest open-end wrench in the set! Also, REALLY wish these hand-guards were available from Adams Arms in FDE to give the builder more options. Nonetheless, VERY happy with this product.
