Zendle tactical bolt release -test and evaluation---

[JAPartridge]

I just installed my TBR tonight (along with the mag release and a hogue hack job)  My TBR is "tight" it has already broken in a little.  I may get some emery cloth and pop it back out and giv it a little polishing, but otherwise she works well.  To be fair, by stock bolt catch was "sticky" as well. Over all I'm very happy with it.  I may also take a bit of jewelers rouge and polish the channel for the bolt release as well.  Now just need more ammo and time!

The hole in the receiver for the TBR "may" have a burr on the bottom end away from the bolt.  Mine did and it would bind and grab and was hard to operate.  I used a drill bit that was larger than the TBR shaft and chamfered/countersunk the hole in the receiver.  That removed the tiny burr around the hole. It works really smooth now and is easy to operate.
