Strike Industries Ambidextrous Magazine Release, Black - ARAMBIMRBK
August 2026 on GunPartPicker
Strike Industries Ambidextrous Magazine Release, Black - ARAMBIMRBK was the most added magazine release on GunPartPicker in August 2026, ahead of the CMMG AR15 Ambi Mag Catch, Black - 55AFF6E, with about 21% of all magazine releases added to builds. That's its 4th straight month at #1. Builds with this magazine release are mostly chambered in 5.56 NATO (67%, then 300 Blackout 17%), split between mid-length (58%) and carbine-length (22%) gas systems, and mostly AR-15 (83%, then AR-10 14%).
Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today all 6 retailers we track have it in stock. Prices barely moved in August 2026, holding around $37.99, so there haven't been real sales lately. Buying today, the lowest price is $37.95 at Brownells, which matches the best price we saw in August.

Reviewed on April 12, 2026Verified with Build
Strike Industries ambidextrous mag release in black has matched anodize finish to my SI lower. Right side paddle is the size you need for quick activation. Drops in with the standard catch spring. Smooth ambi mag drop.

Reviewed on March 12, 2026Verified with Build
Strike Industries ambidextrous mag release in black is one I'd buy again. Right side paddle is angled forward for trigger finger activation. Both sides press cleanly. Drops in with the standard catch spring. Solid SI ambi release.

jebstewart11Ambi paddle exactly what I needed
Reviewed on January 29, 2026Verified with Build
I shoot left handed about half the time during training drills and the standard mag release was slowing me down. The Strike paddle on the right is reachable with trigger finger or support thumb. Both sides need a firm press but not gritty.
