T2K 20 Round Magazine

T2K 20-Round Magazine

The T2K 20-Round magazine will also fit SR-25 / AR-10 and DPMS .308 rifles.

Ours has the spring replaced with a Tubb Precision Chrome Silicon magazine spring for superior performance for the life of the magazine.

"If you're going to store your magazines loaded, you want a CS spring under your ammunition. A CS spring will have much less degradation than a standard music wire spring, and will be totally reliable when you need it."

After all, your magazine IS a spring! After hearing, and experiencing, numerous magazine failures in magazines for these rifles, we decided to produce a better spring.

The problem is rarely in the magazine box and is most often in the follower or spring, and frequently both. Our CS [chrome silicon] spring represents the ultimate in magazine upgrades. It solves virtually al magazine-related function problems, for good.

The Tubb Precision CS T2K/SR-25/AR-10 Magazine Spring provides positive pre-load against the follower. Consistent, constant tension is the key. As with other CS springs, it has extra power and faster rebound. It duplicates factory spring tensions after prolonged storage with full capacity loading and it takes minimal set even after almost solid height compression (full mag) Plus, there is less drag against the magazine side walls for freer movement. These attributes are of utmost importance to the NRA High Power competitor who is frequently relying on bolt stop engagement on an empty magazine and also positive feeding from underloaded magazines.

Our CS spring is angled correctly to locate the follower in its optimum orientation. This design modification alone fixes a majority of feeding problems. Another advantage of this spring is faster, more positive bolt stop engagement, saving wear on the part and also ensuring its correct function.

As with all CS springs, the superior chrome silicon material will perform its job perfectly well beyond the life of any magazine.
