Here's a direct comparison between some weapons.
(Unfortunately I don't have a Mega Railgun and BR yet)
As you can see the AR is tiny though it finally looks like a bullpup.
I think the Brickarms railgun is better than Mega's for the simple fact it has actual space in the middle.
The silver BR is a Brickarms H4/5 variant and it's a real bitch to find online.
I think both DMR's look great, albeit I prefer the bigger scope on the Brickarms mold.
