Came across this on NerfHaven... and it is inspirationally awesome. Solscud has integrated a RoughCut 2x4 into a Retaliator barrel that's attached to a Stryfe with a blue-painted Pinpoint Sight with a Raider stock on there to top it off. It's not only aesthetically pleasing, but could do some serious damage in a game. Below is a video on his Mini Masterkey that integrates a Strongarm. There's also a link to the RoughCut integrated one. I personally prefer the beefy look to the picture above, but I can really appreciate both of these custom blasters.
Check out Solscud's YouTube video below for more information. In the meantime, I'm seriously considering making one of these!
