These FCD/SOLGW Ambi lowers have slight cosmetic blems that do not effect the functionality of the lower.
LRF (Lower Receiver, Forward Controls Design) is a collaboration between Sons of Liberty Gunworks (SOLGW) and Forward Controls Design (FCD).
Machined from a solid block of 7075 aluminum, LRF is an ambidextrous AR15 lower receiver with built-in right side bolt release, designed to use our EMR-A (Enhanced Magazine Release, Ambidextrous), a Norgon Ambi-Catch will also work on the LRF.
Design of LRF was completed in 2019. Due to difficulties of Covid-19 induced lockdowns and subsequent buying frenzies of all things firearms related, production was continuously delayed. Neither SOLGW nor FCD are known to rush development or production, we had used this time to further refine the LRF.
LRF was designed with duty and defense users in mind. Its changes from TDP based lowers are based on ergonomics and better protection of magazine releases (both left and right side):
LRF was designed with duty and defense users in mind. Its changes from TDP based lowers are based on ergonomics and better protection of magazine releases (both left and right side):
* EMR-A (Enhanced Magazine Release, Ambidextrous) fence on the left side.
* Taller than TDP spec magazine release fence on the right side to ensure TDP spec magazine release button stays below the fence.
* Countersunk take down pin hole on the left, when the user pushes the take down pin in from the left side, the pin can be pushed in further, with more protrusion on the right to pull from.
* Built in trigger guard with the same features as our TGF (Trigger guard, Forward Controls), more info: https://www.forwardcontrolsdesign.com/TGF-Trigger-Guard-Forward-Controls_p_178.html TGF has more usable space forward of the trigger, not behind. It also has a “ramp” to facilitate magazine loading for users that use the rear spline of the magazine to index and “rock” the magazine into the mag well.
* Flared magazine well with a larger opening.
LRF’s changes are subtle and wholly functions based, a duty/defense firearm doesn’t concern itself with aesthetics, nor benefit from them. One will not find it decorated with lightening cuts/holes, or obnoxiously large logos. Neither SOLGW nor FCD follow fads.
A tastefully small Cygnus is engraved on the right side of the LRF magazine well to denote FCD’s involvement in the project’s development, one can easily miss or overlook it, and that’s the point, we don’t intend the LRF to be a walking billboard. It’s designed and made for work, not for show.
LRF is shipped only with the right side bolt release and its associated hardware, it is otherwise stripped. You must use the supplied, longer bolt catch plunger/right side bolt release actuator, our advice is to install the left side bolt catch last, especially if LRF has one an ABC/R v3 bolt catch/release.

Nice looks, good finish.
Only problem is the tight fencing around the magazine release button makes it difficult for people with long or large fingers to use. The fencing on the top is right up against the mag release button, which is understandable because of the ambi bolt release, but the fencing on the magwell side is also much tighter than a standard forged lower. This requires the user to be much more precise about how they place their finger on the button to press it. I have to curl my finger a bit to place the tip of my finger directly on the button, rather than just slapping the button with a straight finger on a forged lower.
This may not be an issue for people with smaller hands, but it’s enough of an annoyance for me that I’m considering selling the lower or just using it for a range toy instead of the serious use build I intended it for.
Everything else about the lower is great. SOLGW moving the fencing just a couple millimeters forward would resolve the above complaints.
