WE TRULY APPRECIATE YOUR PATIENCE AND SUPPORT ON THIS PROJECT.
The most robust solution on the market that enables the user to have 3 positions; SAFE, SEMI (Traditional) and SUPER-SEMI. This Forced Reset Selector (FRS) is compatible with mil-spec AR15 (chambered in .223/5.56/.300 BLK) fire control groups and no modifications required. The SUPER SELEKTOR isn’t just a safety, it’s an advantage.
Ultra-Smooth Engagement – Crisp, tactile clicks with no mushy nonsense. Designed for 90-degree throw engagement.
Runs with Mil-Spec Fire Control Groups – Seamlessly integrates with standard AR fire control groups, ensuring flawless function and longevity without modification.
Positive Positioning Without Slippage – Engineered for rock-solid engagement, eliminating the risk of unintentional movement mid-fire, keeping you in full control at all times.
Hardcore Durability – Crafted from heat-treated, 4140 steel and coated in a corrosion-resistant finish, the SUPER SELEKTOR laughs in the face of wear and tear. Rain, mud, sweat—it eats it all for breakfast.
Mechanically Leveraged Design – Our Forced Reset Selector (FRS) reduces wear on your rifle, preserving your weapon’s longevity — unlike forced-reset triggers (FRTs) that accelerate internal component degradation.
Aggressive Ergonomics – Textured, chamfered, and purpose-built for speed. Your thumb finds the selector instantly, even under stress, with no fumbling, no hesitation—just pure control.
Drop-In Installation – Swap out your factory safety in minutes and experience the next level of firearm manipulation (some fitment may be required).
Upgrade your firepower. Own your control. Rule the game.
How to Ensure Reliable Operation:
- This product was designed for mil-spec triggers that do not have a relief cut (that means the rear of the bottom half of the trigger - not the hammer, must be completely squared off)
- Your AR-15 lower receiver must have an FA pocket
- You must use an FA bolt carrier group
- It is recommended to only use an H2 or H3 buffer weight
Compatibility Notice:
-
Certain platforms, such as AR9 variants, may require professional gunsmithing to ensure proper function of the selector lever.
-
Firearms modified to "Super Safety" specifications may not be compatible with components designed for our Super Selektor system, as the Atrius Selector features a solid lever cam design.
-
The Super Safety system incorporates a 15-degree tolerance due to its dovetail construction, which may allow for limited overtravel before the cam surface disengages from the trigger bar.
- Please Note: This Selektor will not work with AR-10(LR308)/SR-25 platforms without significant gunsmithing. In the near future we will be coming out with a model specifically catered to these platforms.
-
Important: All modifications should be performed by a qualified gunsmith. Improper installation or unauthorized modification may result in malfunction or unsafe operation. Use and modify at your own risk. The manufacturer assumes no liability for damages or injuries resulting from incorrect installation or use outside of intended specifications.

My hk mr556 identifies as a hk 416
Was a little worried that it wouldn't work due to bcg but it chopped away smoothly and effectively. I highly recommend this product!

Intuitive, Reliable, and Ready to Run – Selektor is a Winner
I placed my order for the Selektor from Atrius Development Group within minutes of its release on 5/22/2025 and had it in hand just four days later. It arrived in a plain, sealed yellow bag—nothing flashy, but it got the job done.
While I was initially concerned by the lack of installation instructions, that worry quickly disappeared. The install was surprisingly intuitive and straightforward. I mounted it on my 5.56 AR-15 using a BCM mil-spec trigger, and unlike other safeties I’ve used (like the Super Safety, which needed some rifle tweaking), the Selektor worked perfectly on the first try.
Since then, I’ve tested it across multiple uppers with different barrel lengths and calibers, and it continues to perform flawlessly. I’m genuinely impressed with the reliability and ease of use.
Looking forward to seeing the Geissele-compatible and ambidextrous versions in the future—this is one upgrade I’d recommend without hesitation. -
Worked great in ATI lower! Palmetto lower wasn’t drop in though
After getting it ironed out, Functioned perfectly on semi and super selector mode. I’ll explain below:
Did not drop into a palmetto state lower. Selector switch was binding up badly in the hole on the receiver. Definitely a palmetto state issue.
Put it into an ATI lower and used the same mil spec trigger. Worked FLAWLESSLY!!
Selector switch was really stiff and clicked very positively into all positions, and I imagine it’ll get less stiff over time.
