I’m running into expected issues tuning a 10.5 556 for suppressed and unsuppressed reliability
Here’s what I found
All setups using geissele super 42 buffer and spring and dead air sandman S
Barrel is a 10.5 Rosco carbine gas
Fail zero in my experience always cycled faster but has erratic ejection
Fail zero H1 buffer
Unsuppressed slightly overgassed 1 o’clock ejection
Suppressed brass is smacking the deflector hard and going 12-1 o’clock
Failzero H2 buffer
Unsuppressed slightly overgassed with 2oclock ejection
Suppressed is still too overgassed smacking deflector
H2 with BCM BCG
unsuppressed 330-4 o’clock ejection, no malfunctions but doesn’t always lock back last round
Suppressed is 3 o’clock ejection and pretty much perfect
I’m going to try an H1 on the BCM but I believe it will be a bit overdone with the can
Suggestions? I don’t want adjustable gas blocks
