LOOKS SWEET ON A PRO-LITE! Gives great stability, and improves accuracy due to the stock and the RVA. Good Feel to it, and it is adjustable to 4 positions not 3.
ALSO, IT LOOKS SWEET ON A PRO-LITE!
I would not recommend it if you play a lot of speed ball because it my hinder some of your movement. But, you could always take it off and have your gun back to normal in under 5 minutes. Awkward at fist because of your mask but you'll get used to it.
Mine did not tighten up into the correct position so I ran out to tru-value and bought a small thin o-ring and put that on with the existing one. Now it is very sturdy.
Great if your willing spending the money (I had no choice because is awesome!) but you might.
Installation is no prob but you may need an extra small thin o-ring.
I checked and it is the real stock on the m4, not a replica!
And the best thing of all,
IT LOOKS SWEET ON A PRO-LITE!
