Any one else have that problem with this bolt release ? Any ideas ? I have tried turning down the gas and stretching the mag spring .Next maybe a heavier buffer .
Arnie,
If you have 2 Phase 5 Bolt Releases, make sure they are Both Exactly the same? Check the Width of the actual Bolt Hold Open that Catches the Bolt & Holds it Back. If the 1 that works is Wider than the one that Doesn't, that one may be for the AR-15 & it won't work on the 308 platform? Or the Spring & Pin that is suppose to keep it Lifted in the Up Position may be weak, or to small?
I bought an extra Phase 5 off eBay for my AR-15 & found out it was for a 308 instead? I had to Cut The Hold Open Bar in Half ( or Grind Half of it off) to Modify it so it would work on my smaller platformed Rifle, but it finally did!!
They also Will Not work on a Billet Mega Lower Receiver, unless it's one of the Newest Versions of Mega Billet Lowers?
Good Luck Arnie, I Love the Phase 5 Release because it's Rock Solid & is Always there when you need it, & it Looks Great too.
