In an AR-15, what will happen to the buffer spring, buffer, & bolt if the buffer tube is not cylindrical, but octagonal (roughly) and is larger in cross section than the buffer spring?
We're trying to design a thumbhole stock to take some of the stress off the lower. It takes a lot of small plastic bricks (LEGO, Mega Blocks, etc) to build an AR thumbhole stock, & such blocks are not good at precisely locating things such as aligning buffer tubes. What if instead of precisely aligning a buffer tube with the upper, the buffer tube & spring rattled around in a hexagonal channel made of ABS plastic bricks? Ceteris paribus, would the upper still function if affixed to such a buffer system?
Eventually, of course, we'll have to replace the liner bricks - given that would be a couple of $ worth of bricks on the used market that's not the issue.
