That thing bent while I was function testing before I ever fired the gun. I just took it off.

How far back can you pull the bolt past the bolt catch location? Should be just enough to clear the bolt. If the bolt goes back too far then it builds up enough momentum coming forward to break the catch.
I've got a several hundred through my QC glock lower without breaking the catch *knock wood* My problem is the LRBHO isn't all that reliable. |

I'll have to check the travel later today. |

Do you have the new or the old design....the old design the tab to access the follower comes in form the side of the mag......the ne comes in from the front.....the new design also does not have the piece that encloses the bolt catch nose..............and an extended heavy buffer will help with the bolt travel....bolt needs to bottom out about an eighth of an inch from the bolt catch.

OK, there's no over travel from the buffer. It barely goes far enough back to engage the bolt catch.
I'm going to shoot it tonight or tomorrow so I'll report back when I have more info. |

You should have at least 1/8th of an inch between the buffer and catch when it is all the way back...a little more is desirable, 3/16th wouldn't hurt at all.

Did you help design the new one? Nope...Russ and Alan came up with it as far as I know.....I still have a design in the wings.......just haven't had the time to pursue it..... 
I have installed the new one on my lower we are running the blowback prototype on and so far it has eliminated the annoying tendency to randomly lock back in the middle of a mag. |

I put about 120 rounds through it today with no problems. So, it seems that the LRBHO was the problem in my case.
It's a lot of fun to shoot now.

I run the JP bolt and silent capture too. My botch catch snapped in half after 100 rounds or so. I took it out. I may try the new design. Last round hold open just isn't that important to me.
My setup looks almost identical, mur, Samson rail.

Did I hear someone else was introducing a Glock mag lower? Other than Olympic, Lone Wolf, & QC10?

My LRBHO was supposed to be the new design. Last round hold open is not a deal breaker for me, but would be nice. Quoted:

For the couple of people pm'ing, yes it is a CMC 3.5 lb. flat blade trigger. It works flawlessly with the JP bolt and SS.

Get a buffer tube spacer, a longer than standard AR carbine buffer, like one from Heavy Buffers.com, or a $1.75 stack of quarters.
Link it the rearward travel of the buffer to about 1/8 to 3/16" aft of the bolt stop |

I guess you could try it with the retainer in? I was thinking about trying to stretch the spring a little or contact JP to see if they offer a stiffer spring for the 9mm Capture. |

I'm not sure if they make a stiffer spring. |

Greetings, I'd been intending to post a follow up regarding the new LRBHO lever from QC10. I have an early DDLES SFG lower that I was never able to get the last round hold open to work reliably, regardless of the adjustments I did to it. Found a post here about the new design, ordered and installed. Near 100% function so far, at least 500 or so rounds since the swap. Significant improvement in design. Check it out if you've not been able to get the original version to work. FWIW, I have a ramped bolt and a Geislee SSA/E FCG. Good luck to everyone. Regards, Jim |
