GemTech Integra 300 Blackout Upper – The Hearing Safe Review

I have not made my final decision on if I like the .300 blackout or not… This is one caliber that I think I need to shoot another 500,000 rounds through before I can decide. I guess I am just going to need to review more .300blkout guns.

In all seriousness this upper is pretty cool and now that Lancer has released a .300blackout AR mag we can get high reliability feeding from subsonic rounds.

If you haven’t heard about the awesome company that is Silencer Shop Authority here is a link to their website.
