Most Helpful Positive Review Reduced power for 300 AAC BO shooting

Had some issues with cycling on my 300 AAC BO pistol (7.5"), even when suppressed. Figured out it was being caused by short cycling, so got one of these reduced power springs to remedy that. Worked like a charm and now the gun cycles reliably. Definitely worth the upgrade.

perfect for high altitudes/non std ctgs

by Gorobie, from CO, United States Written on October 5, 2026

I have 7.62X39's and 350 legend. On AR platforms. Live @ over 5,400 ft el. Shoot at MUCH higher el's. These springs are a game changer. They work perfect with Odin adj.LW Buffers! Lightweight bolt carriers are a plus as well. Don't drill out the hole, unless you exhaust all these options!

Sprinco Red extra power

by Dan, Verified Owner from NE, United States Written on July 26, 2026

This did just the trick to help slow down unlocking of my bolt paired with a KAW H2 buffer. Eliminated all port pop from
My suppressed mid gas 16” 5.56 and smoothed recoil impulse greatly over the stick spring.

Reduced spring power

by Clay, Verified Owner from LA, United States Written on June 11, 2026

Works well. Using on a 6in 300 blk barreled pistol . The faxon 6in has very little dwell time to build any pressure so this spring helped with short stroking .
