Awesome little gamer add on (EBRv3 ambi/extended bolt release w FDE cerakote) from @Phase5WSI for my 11.5” setup. Love how sturdy it feels as compared to polymer and/or screw-on bolt release extensions
The new EBRv3 from Phase 5 WSI. Redesigned for 2026, it has all the updates features you all have asked for! #Phase5WSI #AR15Upgrades
Added some @OneHundConcepts caps to the optics and light. Really love how this build has turned out #phase5wsi #2ndamendment #ar15upgrades
Something a bit different.. put the Phase 5 CMSA (Carbine Mini Stock) in the @KrissUSA Gen2 9mm. Turned out pretty nice! #phase5wsi #NotJustForARs #2ndAmendment
Starting off 2026 with style is the updated Phase 5 WSI Extended Bolt Release v3 (EBRv3). Designed to be stronger and give the user better control with more room in the trigger area and a better contact point on the bolt catch side. And still 100% MADE IN THE USA!
