I just received a Flattop SIG M400 Direct Gas AR with MagPul adjustable stock, forend and grip. Look for an indepth article in the future but suffice it to say that, well, have you ever picked up a gun and said something like “Oh yeah baby”? The folks at SIG bullseyed this baby-it fits me like the proverbial glove. Can't wait to shoot it and get back to you.
