[ARCHIVED THREAD] - Free Float upgrade help

Posted: 8/20/2016 12:40:54 PM EDT

New guy here and I bought a Windham Weaponry WW-15 with the picatinny rail gas block, My gun.

I would like to add a Free Float rail to it, something around 12-13.5". My question is do I need to buy a new gas block with it? If so, any recommendations?
I was looking at this ALG rail.
Is there anything else I would need? It looks like it comes with barrel nut and wrench

Thanks

Yeah I'm not a huge fan either, got the gun from a friend.

Thanks for the video that basically answered my question. Next question is which gas block would I need/recommend? .750"? set screw/clamp? Clamp seems like it would hold better?

Yes a .750 is what you need. A pinned gas block would be better, but that costs extra to do, and being under the rail, it's not going to be hit hard and knocked off center, so a clamp on should work fine. And you can have the barrel dimpled just in case. I have a couple clamp on gas blocks, but they are .625.. I'm sure people here can recommend a decent one without breaking the bank.

ahh ok, I see you have to drill into the barrel for set screw. That makes more sense. Thanks for the help

Well, you don't have to drill a dimple, it is just a place for a set screw to sit in just in case it was dropped. This is more for a clamp on front sight base like a normal A2 sight.
I have that, and a low profile type, neither are dimpled.

I've also had good luck with blue Loctite and set screws without dimpling. The set screws take hold pretty well.
