I just got my internals installed and when the BHO goes into the actuator hole it keeps the BHO angled too high to pull the bolt back. Anyone experience this when installing your BHO? What is the fix? Any help would be appreciated.

Take a look here:

This is also a concern that I've had, but have not had a chance to test it out yet. I bookmarked the above post as an option to explore and see if that will fix the potential problem, too. |

It doesn't address the issue. With the Bolt Catch Block (BHO) in the DDLES bolt hold open bar, the BHO device sits too high and contacts the bolt when the bolt is in battery. This makes charging the weapon difficult/if not impossible. Note the Bolt Catch Block is partially raised out of its recess.  Is there a specific BHO device that sits flush when installed into the DDLES actuator arm? |

I don't want to hijack this thread, but I am about to assemble my lower as well so this is good info for me since I have never played with one before. My question is when I put a magazine in the stripped lower that I just received, the magazine does not lock in place hardly at all. Is this normal prior to assembling the rest of the lower parts or will the mags only hold once the bolt catch is in place?
I don't want to start assembly if the mag catch or magwell has a problem right off the bat. Also, the magazines fit quite loosely in the magwell. Thanks, Esox |

Greetings, I had the same problem with my DDLES Glock mag 9mm when I first go it and was also hesitant to continue on with the build. It seemed to clear itself up after a couple dozen insertion/removal cycles. No problems since. Hope yours does the same! Regards, Jim Quoted:

| Okay, apparently I wasn't jamming (and I mean jamming) the mags far enough up the magwell. After pushing really hard...to the point of being scared of damaging something...I got it to lock up. Now it is getting easier each time. Apparently before I never even got it to lock up, although it did hold on its own due to friction I guess. THANKS JIM! |

I have two of these lowers and one is good to go and the other requires me to jam the mag to get it to lock up. If it doesn't clear up I may pull the mag stop that is left of the extractor and lightly file the bottom of it until I get the desired lockup I am looking for. |

It turns out that the standard BHO device made contact with the underside of my bolt, causing the trouble. I ground down approximately .030 off of the top of the BHO, and all functions correctly! Also, make sure you replace the standard BHO spring with the one provided by DDLES, otherwise your mag will be fighting heavy spring pressure. Prib |

Greetings, You're welcome. It should also improve with use. As I noted, mine was really bad initially. Think I have somewhere about 600ish rounds through it now, mostly with 15 round mags. It's MUCH smoother. Just needed to work things in a bit. Best of luck! Regards, Jim Quoted:

As you know, the factory BHO is tilted up a bit from its normal position because of the DDLES mouse trap that actuates it.
Some 9mm bolt carriers come into contact with the factory BHO because it's tilted up a bit. Some do not. You can grind on the bolt catch - but if you remove too much material you may keep the bolt catch from working at all. The solution is to grind a bit off of the bottom of the carrier where there is contact. This portion of the carrier serves no function and so grinding a bit of it away is not a problem. This is evidenced by the fact that not all bolt carriers make contact at this point. I have been EXTREMELY satisfied with my DDLES small frame lower. Once I relieved the bottom of my bolt, I have had 100% reliable function. The mags drop free and lock open on the last round. The lower is very nicely designed and the fit and finish are as good as any I've seen. I do have two complaints about the DDLES lower: high price and limited availability. |

Not everyone's bolt carrier looks like this. It's a REALLY old Colt (I believe) that I've had for 12+ years. Some newer bolts sourced from other suppliers that I've seen recently - their slot in the middle is MUCH wider at this point and there is no contact at all with these.
If you put a little paint on the right side edge of the BHO, it will leave a mark at the point that you need to remove.

I have had the bolt prematurely lock back a few times. With the reduced spring there's virtually no pressure on the BHO so it can pop up -- say if you're shooting the gun while it's horizontal vs vertical. For now I've just put in a standard spring and am foregoing the BHO function. I'm coming from a Colt pattern setup which didn't hold the bolt back either so no loss!

When you say no pressure- does the button offer no resistance/almost rattle around on the lower? Maybe try stretching the spring a bit? That is where I am on mine... fine tuning. |

There is zero resistance until the hold open is almost fully up. It can flop around. Turn it upside down and the holdopen will be engaged.
Maybe I'll try stretching, or just using different (light) spring. But I'd rather have no LRBHO than one that ever engages prematurely. Quoted:

Thanks for the reply. It is a fine line, a standard spring is too stiff and will not allow the BHO to actuate after the last round. A weak spring will allow the catch to rattle, and it can pop up prematurely and lock the bolt with rounds still in the magazine. You could stretch your spring or install a standard spring and it should override the LRBHO function. |
