AR gas block

Hello all,

I am working up a 6 by 45 AR build and i just had my smith machine down a shilen blank and drill a midlength gas port.

Now.... I want to hide a gas block beneath the handgaurd... any and all suggestion will be great, but i don't want to use more than 150 dollars out of my budget for the handgaurd, or 75 dollars for the gas block.

I'm open to tube and four rails, as long as they are free float.



I have decided on the Troy micro gas block, how i need a rail

Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1

The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
