Hey guys I own a Remington 700 SPS Varmint in .308 caliber. My problem is that it has a internal magazine and I would love to have a detachable magazine system. I've looked into them and came up with three to choose from. The choice are the CDI Precision, H-S Precision, and the Seekins Precision detachable magazine system. I'm leaning towards the seekins precision DMS because it has a push button release on the side. Wanted to know if any of you guys had any experience with any of them. If not any experience with the company that makes them.
