Found this photo in a Bullpup group on Facebook. Daniel J. modified his Bushmaster M17.
Hello, I have a Bushmaster M17. I think it’s great for the amount of money I am into it. K&M trigger and magpul butt pad adapter with limb saver pad. I shortened both barrel & received, added cooling holes to the sides. I drilled and tapped the front and added a short section of rails. In the near future I will get rid that BS sight it came with (bought it used) And use a different rail.
