11.5” Colt FBI Barrel Ejection

[Clint]

Has anyone done a back to back comparison between the colt gold spring and the two sprinco options?

I'd go with a Colt "gold" spring, or one of SAW's green springs.

What is a SAW green spring?

I think it is a reference to this.

How it turn out?

Great. With the H2 buffer and Colt spring it ejects m193 at 3 o’clock and .223 at 4. Brown Bear will not cycle. I want to see if a H1 buffer would allow for cheap Russian ammo to be used if needed. May have gone .070 in hindsight.

Dropping down in buffer weight speeds up the cycle and allows proper operation with lower power ammo.

Sprinco has a enhanced and a extra power, which one is recommended? with or without the insert?

With insert
