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 is the seventh most added bolt catch on GunPartPicker so far in October 2026, behind the Troy Industries AR-15 Ambidextrous Bolt Release, with about 3% of all bolt catches added to builds. Up from #11 in September. Builds with this bolt catch are mostly chambered in 5.56 NATO (69%, then .223 Wylde 13%), split between mid-length (46%) and carbine-length (34%) gas systems, and mostly AR-15 (94%).
Availability is good: it was in stock at one retailer or another nearly every day in September 2026, and today 7 of the 8 retailers we track have it in stock. Prices barely moved in September 2026, holding around $29.95, so there haven't been real sales lately. Buying today, the lowest price is $29.95 at Primary Arms, which matches the best price we saw in September.

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.
