Radian
Overview
The Radian Extended Bolt Catch is a steel component designed for enhanced functionality in AR-15 builds. Its extended design allows for easier manipulation when locking the bolt back, which can be particularly beneficial during reloads or malfunction clearing. This bolt catch is commonly found in builds featuring a carbine gas system and chambered in 5.56 NATO, making it a practical choice for a wide range of applications.
Radian Extended Bolt Catch was the seventh most added bolt catch on GunPartPicker in August 2026, behind the Troy Industries AR-15 Ambidextrous Bolt Release, with about 3% of all bolt catches added to builds. Down from #6 in July. Builds with this bolt catch are split between .223 Wylde (33%) and .458 SOCOM (33%), mostly on carbine-length gas (75%, then pistol-length 25%), and mostly AR-15 (86%).
It was in stock most days in August 2026, and today 8 of the 9 retailers we track have it in stock. Prices barely moved in August 2026, holding around $29.95, so there haven't been real sales lately. Buying today, the lowest price is $29.95 at Optics Planet, which matches the best price we saw in August.

The extended Radian catch paddle is meaningfully larger than the factory part. Easier to hit with the trigger finger when locking back an empty mag. Lines up with the magwell properly. Anodizing is consistent across the visible faces. Solid upgrade.
