PDQ Ambi Bolt Release Verdict?

[Brazos_Jack]

These look really interesting. I read a lot of glowing reviews on some blogs. I've also read of some problems on some several year old posts on some other forums. Have any past problems been addressed? Are any of you using these. How are they working out?.

I have one that I performed the Dremel mod to my Bushmaster lower, have had zero problems with it. And I have an Aero Precision gen2 ambi lower receiver as well and also have had zero problems with it

No link? No pics? No nothing?

I tried one and regret cutting the lower for it. For me it's hard to use for locking the bolt back, which was the only function I wanted from it (don't care about a right side bolt release). And it can cause failure to lock the bolt back on an otherwise properly functioning gun. So I have a lower now that is cut for one but I took the thing off of it. FWIW mine didn't break/chip like some of them apparently did.

Was it pressure from the port door that caused the failure to lock back with the PDQ? Did it happen on the last round of a magazine or when operating the charging handle with an empty mag in place?

I have 2 Aero’s and one modified lower with the pdq. It does work but with one of my aero’s the bolt doesn’t always lock back on the last mag. I don’t know if it’s the port door pressure or if it’s the Pdq has too much mass to overcome.

"but with one of my aero’s the bolt doesn’t always lock back on the last mag. I don’t know if it’s the port door pressure or if it’s the Pdq has too much mass to overcome"

I think the problem is the combination of the two.

I've also looked into things like the Magpul BAD and the Troy. It looks like none are "ready for prime time" as they come from their respective vendors.

I've read of one guy who made his PDQ 100% by ginding away about half of the part that extends from the starboard side of the receiver, drastically cutting the weight and removing most of the arms material where it contacts the port door.

It seems that for $60 bucks, the vendor should make them this way to start with:

Any updates on this? I saw the new HK416 ambi bolt release and thought it looked remarkably like the PDQ... At least in LAVs video.

If anyone is interested in the PDQ lever or the HK version, I would suggest just buying an ADM UIC lower. I have several, have never had any problems with anything not working the way it is supposed to, and use my trigger finger to both lock the bolt back and release it. At this point the only AR lower that I own that is not an ADM UIC lower is an AXTS (pre name change to Radian) AX556 lower that is SBR’ed..
