Hey All,
I looked over several threads on ASC and Reddit trying to find the main differences between the two clones. From what i found was.
Madbull:
1. Made provisions to not allow the ability to include a gas block
2. (Trades?)
3. Nicer finish
ACM:
1. Larger screws for barrel nut (could be wrong)
2. Has two different sides for the barrel nut (AEG and Gas)
3. *From what i heard the ACM has a thinner shell which could cause tightened keymods to not fit at all.
The two are kind of similar in price give or take a 15-25$ difference. From your experience which would you prefer?
This will be going on my RM4 (going to rear wire of course

)
Thanks,
JW
