INTRO:
Here is a review of the various 6.8SPC magazines that are currently available. This is based on the newer versions and not the old versions.

1. Barrett:
A. Positives:
1. 30 round magazines that load smoothly. Only company that makes 30 rounders at the moment.
2. Metal anti-tilt followers.

B. Negatives:
1. Reliability is hit or miss.
2. Expensive. ($40-50).
3. Have to load the bullets short (approximately 2.255").
4. Very long. 1" longer than PRI and C-Products 25 magazines.

2. C-Products: (2008 and newer.).
A. Positives:
1. Cheap. ($12).
2. New 25 rounders are very reliable.
3. 5, 10, 17, and 25 round magazines available.
4. See #1.

B. Negatives:
1. Can't load the bullets out as long as the PRI. (approximately 2.285").
2. 17 Round Straight mags are not that reliable.

3. NEW PRI (Waffle Pattern):
A. Positives:
1. Can load them out to 2.305"
2. 5, 10, 15, and 25 round magazines available.
3. Fit better in the magazine well.

B. Negatives:
1. Reliability is hit or miss.
2. Expensive. ($30-40).

4. OLDER PRI:
A. Positives:
1. Reliable.
2. Can load them out to 2.305"
3. 5, 10, 15, and 25 round magazines available.

B. Negatives:
1. Expensive. ($30-40).
2. Issues with the followers being too short (Not actually PRI's fault as the followers are made by Magpul.).
3. Fit very tight in the magazine well.

CONCLUSION:
For most uses, the C-Products 25 Round Magazines are the best bang for the buck. The only negative about the C-Products Magazines is the springs are a little weak. I highly recommend replacing them with the ISMI or Superior Shooting 556 30 round magazine springs, which will last forever. For Precision Shooting, the PRI Magazines are a better choice because they allow a COAL of 2.305".
