SBF. Should’ve Been Factory.
Same dimensions as the original AUG® safety selector, without the sharp edges.
Tapered edges, textured ends, 6061 aluminum and compatibility with both Standard and NATO A3 M1 stocks.
Simple upgrade. Immediately noticeable.

The STD is great for Direct Thread options.

Yes, a rimfire can is fine being hand tight. But then we couldn't show you our cool monocore Resonance!

So enjoy a little of both..

The big ones hurt more.

Especially when you time them with a crush washer.

5/8-24 Heresy Silencer Timing Device. No crush washers. No stacking shims. Just properly timed in under 60 seconds.

Lot's of comments on the last video about how the device in the video didn't need to be timed. Correct, just a reposted video. Check this out to see why the STD is the superior timing option.

Crush washers will get you baffle strikes.

Shims take a some time & finesse to install.

STDs takes less than 60 seconds.

Keep sending us your AUGs. We’re celebrating AUGust the right way and loving every setup you guys have shared so far.

Stock, modified, weird, clean, well-used... we want to see them all.

Bonus points if you know who this is. 👀
