I can think of LMT MARS, LWRC, and newer KAC SR15. This thread has so far revealed the ADM UIC, POF P15 Gen4, PWS MK1 MOD2-M, and Griffin MK2 as well.

The Radian deserves a mention, but it's controls aren't truly "mirrored", in that the right side bolt catch doesn't have exactly the same functionality as the left. The magazine must be absent to lock the bolt to the rear.

The Dirty Bird MCF-A shouldn't be ignored either. It seems to perform even more conventionally than the Radian, but with a unique device that almost inspires more questions than answers.

For the purpose of this thread, by fully ambi, I mean right side bolt release and catch.

I see much more utility in a right side bolt catch than I do in a release. My left hand is already near-enough to the left side paddle, when I am inserting a mag, that it's easy enough to use it to send the bolt home. In the context of malfunction clearance, that right side bolt catch is what really saves you from having to do some more awkward manipulations.

I'll clarify that I am considering all this from the perspective of a right handed shooter. Also, I am not shopping for one; nor do I necessarily even think they are worth what the proper ones cost. I have a MARS-L lower; it is very nice. However, I have yet to SBR it, so it sees little use. My other lowers have ambi safeties and Norgon-style mag catches, but that right-side bolt catch is really the most important thing, IMO.

In most circumstances, I don't think any of us experience malfunctions enough to really make that functionality worth the money. I am posing this question after a training event that utilized blanks, and had me and others doing malfunction clearances at a higher rate.

Sons of Liberty did a colab with Forward Control Designs.

Except it doesn't have a right side bolt catch. There are plenty of offerings with right side bolt releases; not bolt catches.

Probably doesn't count but

ADM has them, $420 for a stripped lower.

The once lauded but frequently maligned Magpul BAD Lever works and works well.

The ADM is indeed truly 100% ambi. Looks like the best buy of the bunch too.

I hear ya, on the BAD. I have had one in the past.

In the same vein as the BAD lever, which I have and have used for a long time, Phase 5 makes an integrated version I've been thinking about trying.

Love the Phase 5

Not sure if it's sold separately but POF has a billet lower that does all of that.



The ambi bolt hold is in the trigger guard where you pull the charging handle back and press the tab upwards to lock. There's no chance for you to set off a round because your other hand has captured the bolt.

You can get that POF lower all by itself, and it is certainly 100% ambidextrous; cool. Halfway between the ADM and LMT, price-wise.

I will say that I prefer the more "mil-spec" look of the options from LMT and KAC, but they come with that pesky price tag. Also, I don't think the KAC (and LWRC) ones can really be had outside of a complete rifle.

It'd be interesting to interact with the ADM, POF, and LMT side by side, to see which method of bolt catch engagement feels most natural.

I appreciate the feedback.

I think Radian came up with a clever idea and efficient design for their ambidextrous ADAC lower. The right-side magazine release also pushes up the bolt catch-so as you drop the mag and pull back the charging handle, you can also lock your bolt.

That Radian is darn close. Neat idea.

I understand that, in most bad malfunction scenarios, you're getting rid of the mag. However, in the recent context of training with blanks, I wanted to reuse that mag. The problem was the ammo and/or BFA; not the mag. That being said, the Radian doesn't allow you to lock the bolt back with the mags still inserted, which would be advantageous if I want to reuse the same mag.

Though I could remove it, and work the charging handle with the hand I am holding the mag with. That's exercising the dexterity a bit though.

Imo the best on the market is the LMT Mars-L. I agree with a poster above about looks, I like plain Jane lowers, I don’t care for most of the billets made at the moment.

If the catch is of specific concern I've seen most lefties use their index finger on the standard left sided control. The release is where the PITA is. Most insert and roll their fingers up or roll the rifle and hammer the release. I may not be describing that well.

This thread has been about the benefit of mirrored controls to everyone, in general; not just lefties.

Their SBR is SEXY. Pricey, but sexy.

Being lefthanded I found the Forward Controls Design ABC/R v3 augmented bolt catch/release serrated & rearward biased the best design.

Griffin Armament MK2

The griffin MK2 looks to be the cheapest as well.
