    That little cut isn't going to make any practical difference in the strength of the lower. Remember, the lower takes very little stress.

    The cut is very easy to make. My concern is whether or not I could release the bolt with my trigger finger. Looks like a bit of a stretch

    PDQ is wokrs same as HK416A5 ambi bolt release (HK version is clever design and works good with dust cover, PDQ is more crude approach and works better with dust cover removed). I wait to get OFM HK part, so for time being I installed PDQ. I already shot IPSC rifle match with it and it worked fine. I prefer it over Magpul BAD.

    I like it for a pre-milled lower, but I'd rather stick with my Troy ABR than break out the Dremel on my DD lower.

    I agree with the general consensus here. I wouldn't mind a pre milled lower with this in it. But I am not going to modify an existing lower. I saw MAC did a video on this a while back and I thought the same thing then..
    Tell my tale to those who ask. Tell it truly; the ill deeds along with the good, and let me be judged accordingly.

    Does the PDQ hit the upper receiver when you lock the bolt back? It's looking like it in the pics I'm looking at.
    I'll stick with the AXTS A-DAC system.

    If you guys are afraid of making a little cut like that on your rifle, you'd better stick to ARs. Heaven forbid any of you attempt to build something as simple as a FAL

    I really like the innovation that we've been seeing recently with lower receivers. We now have five kinds of ambidextrous bolt controls on various lowers:

    - Simple bolt release button with no bolt catch: KAC, POF, Lancer, Mega, Seekins, Spike's.

    - Bolt release / bolt catch combo button: HK 416A5, Remington RGP, PDQ.

    - "Ping pong" bolt release / bolt catches on both sides of lower receiver: LWRC Individual Carbine, S&W M&P 10.

    - Bolt release button and mag release/bolt catch combo: AXTS AX556.

    - Bolt release/catch at bottom of trigger guard near mag well: Bushmaster BAR-10.

    Pretty neat, if you ask me.

    Good list.

    IMO... it's a nice feature, but I'm not sure I get the big deal. If everything is going well, you shouldn't need to lock the bolt back. If things are going poorly at distance, reaching your hand around to pretty the ping pong down and rack shouldn't matter. If things are going poorly close up, you don't have time to clear a malfunction so going to another weapon is key.

    I guess I get the appeal for gamers that have to lock and show clear all the time. But, for the most part, this seems like a luxury feature. And there is nothing on earth that would have me drilling and dremeling on a fighting gun just to add a luxury feature. Just my opinion though.

    ps> I have the Mega ambi release... If you're not careful or used to it. Expect to now and then drop the magazine instead of the bolt

    I don't get it. I mean I DO GET IT but I fail to see it providing actual value. My motor skills can be spotty at best under duress and this screams "fine motor skill" to me while over-complicating the AR's controls.
    Never sit at the bargaining table with an empty stomach.

    It's a lot faster to clear a double feed with an ambi lower than a legacy one. It's also a lot more fluid. Making anything easier under stress is good in my book. Other than that an ambi lower really isn't faster or better. But there is something to be said for pretty much never having to take your firing hand off the grip. Just gives you confidence that you can control the gun better. That's my experience with the AX556 anyway. Idk about this PDQ thing.

    Personally I don't like the addon ambi stuff like the BAD lever or this PDQ. I'd stick with a lower made for it like the LWRC or AX556.
