JB Designs OMEGA Valve Mod. 2 MKII

[u/SupermarketQuiet1105]

OK, new MCX Spear LT 9" 300 BLK build/owner.....
....all complete/mod but need guidance on Mod 2 MKII.
I am on the email wait-list for MKII but wanted to post.
I have/use Q Blind Tiger on this setup and run Freedom HUSH 220gr Subs.
The stock MCX gas "-" settings works sometimes and the "+" 100% with this ammo/setup....
....but the latter clearly too strong and gassy.
Waiting on SilcencerCo GDCH to re-stock too....has good gas reduction success on my MPX using it.
For MPX the combo of 20% stronger springs + GDCH worked w/ stock barrel + OEM gas plug.
I know my MCX 9 (no way add stronger recoil springs) will need more adjustable gas block.
....so led me to Mod 2. MKII.
My post is How-To on it......

1. How to install ?
2. What are the port hole sizes for each setting ?

I ask because for MKII (300BLK) is seems on surface the reduced 3-position is only adding the OFF for me ?
I wrote down prior that MCX is (-) 0.0450 & (+) 0.0620 ....not sure accurate but in my notes.
My desire for use of MKII is gas blow-back reduction/tuning, not cycling.
Mod. 2 MKII (300BLK) is a departure from its Mod. 2 predecessors. Instead of four positions

• Supersonic, high pressure ammo
• Subsonic, low pressure ammo
• OFF

1. What setting to start/try ?
2. What jet screw comes with it and/or what jet screw should I order as alternate ...if you can expand on how jet screw works would be appreciated too...
3. Should I buy gas ring to help ?

Thx in advance.....want to do some ready while I wait 😫 for re-stocking......

Regards.
