Guntology PDQ Ambidextrous AR-15 Bolt Release

Installation was very straight forward, fit was good. I accomplished the installation with a hand file and went slow, this is not an installation for 'A Dremel and a dream'. Much easier to drop the bolt on a load/reload. I like it better then a BAD lever, which I have on all my AR's. Now for the downsides. If your lower has excessive side to side play in the bolt release this will cause the lever to hang slightly as the unit tends to torque when the follower pushes up on the lever. The second issue is that the lever has to not only overcome the torque issue but also the spring tension of the dust cover since the dust cover rests on the lever putting downward pressure on it. I swapped lowers with a side charging upper I have and with some well placed lubricant everything is working great. It still gets hung occasionally when manually operating the bolt with an empty magazine but while actually shooting there is no issue since the force of the bolt hitting the end of travel will jar the lever loose and engage the hold open, even with an upper with a dust cover. With all that said, I will still get one more and would recommend you try one for yourself. Installation is easier than you would think, about 2 hours start to finish. Hope this helps.

After building several AR's I wanted something more difficult to add to my builds. Sadly this is not more difficult, it is however very satisfying to add. It is more easy than I thought. I have purchased more to add to my AR's. I really enjoyed putting this on. If you can bring yourselves to cut into a receiver you will feel greater satisfaction with your build. Buy it, I have.

With a small amount of machining this Ambi bolt release makes the life of a lefty a lot less awkward. Truly a great product!

This is a great up-grade to any AR 15 style rifle or pistol. I put one on a 300 Blackout pistol as well as a couple or rifles. The install is easy and took me about 45 minutes using a drill, file, and hacksaw. It works great and will order more.

I was a little hesitant because of the modifications I would have to do to my lower to put this in....I took my time and realized it was EXTREMELY easy to do.....just take your time when you do it for the first time or two. This is a feature that I feel should be a standard on all AR15s. I have put these into all of my lowers. Before this, I had Magpul BAD levers in all of my rifles...but I kept actuating them inadvertently because I have pretty fat fingers. Add to that, the fitment of the levers wasn't always 100% and there was usually a bit of wiggle in all of them. They're all gone now because this simple lever does the job easily and is very functional
