Looks good man, did you use thread locker when reinstalling your screws? I noticed the factory had locked everything so I went ahead and cleaned my threads and used blue on them. Let it cure for a few days before shooting. I’m over 200 rounds with the micro front end and zero malfunctions. Everything’s running well. It does sound weird for a blow back 9. You’ll see, take your cab off and bang some loud rounds I think it’s harmonics from the aluminum handguard and the bbl. not bad but sounds different. It’s aweome though!
Thanks! I used blue on everything as it went back together. I’ve used blue on a lot of stuff and never had an issue. I noticed the harmonics you mention just in function testing after I got it back together. Something definitely had a new sound to it.
