I have a Remington 700 XCR with a 26" barrel that I would like to mount into a chassis. I have looked over many different makes and styles of chassis and I have found an interest in the chassis systems where I can add the AR-15 type of butt stock of my choice. The three chassis manufacturing companies that I have found are MDT LSS Gen2, Ultrdyne UD5, and the Rival Arms. This will be for a hunting rifle and field target shooting for fun and practice. Of these three chassis which do you have experience with and what are your overall thoughts and opinions of them. Thank you.
