Absolute must have if you want to add anything to your AUG. The adjustable gas tube makes shooting suppressed an absolute breeze with a switch you can adjust with your fingers. I will say that when I got mine the gas regulator/switch was stuck, but the team at Heresy provided first class service and sent me a new regulator within 2 days. Definitely going to be purchasing more AUG accessories from them in the future.

Finally, a company that has identified the major deficiencies with the AUG platform and produced a product that addresses all of them. Instead of shelving the AUG in favor of others that could run accessories and be suppressed, I can now work the rifle the way I’ve always wanted to. Great job, team!
