Compatability Issues

[Hawk in WY]

My experience is that parts from different suppliers usually work well together.

Not this week.

Origin .223 action in KRG Bravo chassis with a MDT magazine. Bolt overrides the round in the magazine. The bottom metal is not the one with the barricade stop with the adjustable mag catch release. I plan to call MDT asking if they have a longer mag catch release.

ARC CDG long action 7 PRC, McMillan stock speced for this combination, MDT bottom metal, MDT five-round metal magazine, and a three-round plastic magazine. The bolt drags on the magazine follower with both. The three-round mag is better than the five-round mag. Washers between the bottom metal and the stock fixed the problem, but this doesn't seem like a very professional solution.

I suspect the answer is to pillar bed both rifles, which is probably a good idea anyway.

This industry needs better standards.

How do you have a bravo that has bottom metal? You can open the feed lips on it to raise the round up. The washers will probably be fine in that stock. You can also look at filing down the mag catch if it’s riding too high

Correct. The Bravo does not have separate bottom metal.

I will try opening the feed lips and live with the washer solution.

I have adjusted the mag catch on other builds. With a hunting rifle, a loose mag is a problem. The washer may be the better solution.

If you don't want to bend feed lips for the KRG Bravo chassis, buy the adjustable mag catch trigger guard.
