@KevinBrantlee @Mrgunsngear Cuz idk how to use Twitter sry. I thought I was just answering a product question but yeah the link shared by @Mrgunsngear is a site using our imagery to sell fakes.

@Mrgunsngear Why is Atrius Development saying this is a fake and not to buy? But they are telling another guy that it will work with his lower? Crazy!!

Any homies out there have this DL44 from @CMMGinc ? We’d love to confirm compatibility 🤓

@Mrgunsngear That would be a fake. Please avoid purchasing from them. We checked our dealer list and they’re not on it.

The world you grew up in no longer exists.

ICYMI: we've got upgrade kits for current FRS owners wanting to gain drop-in compatibility with Geissele triggers!

A quick note, we address the main difference between the new FRS G-Lever and our original FRS.

@Rando51865268 Unfortunately, it doesn’t work with the X or lightning bow versions we’re still working on that!

@atriusdev Will this work on a SAAE-X (like in a Super Duty)?

A quick note, we address the main difference between the new FRS G-Lever and our original FRS.

@RealJayFranksen So if you buy our original FRS (single side selector) or FRS Ambi, there’s a whole host of trigger compatibility listed on our website. It’s just that this model is the first to be compatible with the Geissele SSA, SSA-E, and G2S triggers.

@atriusdev So your products only work with Geissele triggers?

@EOTECHInc Sheeeeeeeeeeesh
