Rate reducer and the 300 BLK

[eastern_hunter]

AAC,

Years ago, I bought a carbine length M16 rate reducer from the original AAC. Works fine for 5.56 and makes short 16s much nicer to shoot.

You fellas ever try one of these things with 300 BLK?

Just wondering how much I'll have to change to play with the 300 BLK upper on the M16 lower.

Thanks!

The recommended buffer for AAC uppers is already the best weight. So using a rate reducer will just reduce reliability.

They are useful for overgassed guns.
