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!
Weaknesses:
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.
Conclusion:
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!
