Ok, that what I was hoping...a lot of people get them so they have them.
I don't think it matters what kind but Superlative has a good rep, and they claim to be the inventor of the bleed off. Anyway, whatever one you get, you can follow this recommendation for adjusting it assuming it's on correctly:
You're not worried about accuracy right now just functioning. Make sure your gun is oiled and don't be chincy with it.
1. Turn the adjuster all the way closed
2. Load one full magazine
3. Fire one round – it’s not gonna do anything other than go out the barrel…the BCG shouldn’t cycle
4. Turn one click open
5. Fire a shot
6. Continue this until the bolt cycles and ejects a casing and feeds a cartridge
7. AT THIS TIME, put two cartridges in an empty magazine - you can put three or four but minimum two
8. Fire both cartridges and see if the BCG locks to the rear on the bolt face (not the carrier)
a. If it does, open up one more click and leave it
b. If it doesn’t, open one click and repeat step 7 & 8 until it does and Step 8a
I always start with the adjuster closed and work up. If it's done right, most of the brass will be 2-4 o'clock. Some people weird out about anything 2-3 but it doesn't really matter as long as it's functioning and there are no malfunctions. I've watched people chase their tails over it.
