Without a doubt, the AKTIVE Buffers by CTS Engineering would be one of my first picks for any AR-15 or AR-10 rifle with a fixed stock. They have a solid stainless steel buffer body with an overall weight that has been finely tuned for excellent performance in those specific platforms. But even more importantly, they have a shock absorbing piston on the front end and a far superior bumper on the rear end for a dual stage buffering action. This action really does make a noticeable difference in the smoothness and recoil of the weapon. I’ve seen a lot of buffers over the years and this is probably the best bang for the buck of any buffer on the market. The AKTIVE buffers are made in both a standard and an anti-tilt version in so you can have every feature you could want on a buffer. They run as smoothly and quietly as any buffer system on the market, so if you are thinking about using a suppressor, they are a great choice for that too. Heavy loads or light loads? No problem. Match them up with a tuned, ground and polished JP buffer spring for the quietest operation possible. You will be very pleased, I assure you that. If you have a fixed stock AR type rifle, this is one of the best upgrades you can buy for it.
