I've had the lower reciever and Magpul Stock for awhile - curious to see how the gun shoots with the Magpul MIAD grip and the 16" midlength barrel - they say the midlength gas systems run smoother then the carbine length gas system - that coule just be urban legend...realistically it makes sense.....will post feedback once I break it in.....
The Magpul MIAD grips are great for possibilities - the internal core will store spare parts, extra rounds, etc.......but for overall comfort I don't think the Hogue grip can be beat. The battlegrip fits an extra AR bolt - maybe overkill - though my guns RARELY break I like to have spare parts on the weapon. This is my first Yankee Hill Machine rail system - and a hell of a value - I've used a number of rail systems - for the price I don't think anyone could argue about their products. They also make the Phantom Flash hider - good product but I like the Smith Enterprises Vortex G6 flash hider myself.
