ANSWER, The EZ-LOAD FLOORPLATE.
It’s a completely new way of loading your magazine. When extended and locked, the EZ-Load Floorplate leaves the body of the magazine empty allowing ammunition to be inserted with minimal resistance. In the EZ-Load Magazine, the constant tension spring found inside a traditional magazine has been replaced by the EZ-Load Floorplate’s telescoping tube (shaft).
The EZ-Load Floorplate is similar to a collapsible umbrella shaft. The floorplate is securely attached to the patented telescoping tube. The connected shaft is comprised of a stainless-steel tube surrounded by three additional tubes, each larger in size than the next. They smoothly slide over one another maintaining optimum spring tension on the ammunition column as each round is fired.
