Hey guys, this is my first thread here, so bear with me. I was messing around with a rear wired G&P AR15 the other day (rewiring, adding mosfet, etc.), and couldn't fit the custom mosfets that I build in it anywhere. After some consideration, I made this: Sorry that it's blurry, I took the picture with my sucky phone camera. Essentially, it is a piece of 1'' steel conduit cut so that it fits as a spacer in the buffer tube between the washer and the receiver/gearbox. It gives the mosfet plenty of room inside the buffer tube, out of view, and out of the way of trying to remove/install the buffer tube. Here is a diagram showing the exact location and use of the buffer spacer: What do you guys think? Is there another easier or simpler solution?
