Normally, I like keeping my stuff 100% OEM unless there is a good reason (i.e., SureFire flash hider QD so I can attach the SureFire suppressor, Geissele trigger, etc.).
I have 2 MR762s. One I left the barrel length as is. The other I chopped it down to 13". Although the 13" barrel works great when suppressed, it has issues cycling when shooting without a suppressor.
I don't see myself shooting the 13" MR762 without a suppressor (my head hurts when shooting the 10.4" HK416 without a suppressor let alone the 7.62 caliber), but what happens in the 1% chance the suppressor gets stolen by a feral zombie??
Jokes aside, I wish I had a gas block that allows me to shoot suppressed and non suppressed without any cycling issues. I understand the laws of physics means that my MR762 is cycling too hard when shooting with the suppressor (if if cycles reliably without a suppressor), but I personally prefer non adjustable gas blocks. One less thing to futz around. One less thing to forget to adjust, etc.
I am probably going to lean towards keeping my OEM gas block, but definitely appreciate the heads-up.
Do post pics when it is done!!
