Sons of Liberty: Forward Controls Design LRF Ambi Lower Receiver
Sons of Liberty Gun WorksWhen purchasing an item on pre-order, do not add additional products to the cart. Any additional items will not ship until the entire order can be fulfilled. Orders will be shipped in the order they are placed.
The 2025 SOLGW x FCD LRF ambidextrous lower receiver retains its signature flared magwell and ambidextrous controls while adding six key improvements, including an enlarged receiver extension ring, a modified beavertail, and a tighter lug fitment. These enhancements create a seamless blend with various uppers, improve compatibility, and simplify maintenance without compromising the battle-proven design.
Unchanged since its release, the LRF still features the same generously flared magazine well, signature trigger guard geometry, ambi magazine-release fencing provision, and ambi bolt-release mechanism.
The following enhancements have been added for 2025:
- Enlarged support ring for the receiver extension – creates a seamless blend with both Broadsword upper receivers and forged uppers, while strengthening the critical buffer tube junction
- Modified beavertail contour for wider pistol grip compatibility
- Tightened lug fitment – providing superior fit with various upper receivers
- Enlarged trigger pocket – material removed behind the magazine well for improved trigger finger clearance and reduced weight
- Beveled selector stops – steeper bevel more closely mimics standard forged selector stops
- Bolt catch roll pin relief cut – simplifies the removal of the roll pin when swapping bolt catches
The LRF includes the proprietary parts necessary to integrate most any bolt catch of your choosing and is available fully assembled, stripped, or in complete firearms from SOLGW.
The LRF lower receiver has our Rebellious Stripes design on the left side, and the FCD Cygnus logo on the Right. It includes the proprietary components for the ambi bolt release and is compatible with all other standard lower parts kits. Due to the already enlarged magazine well, aftermarket magazine funnel attachments are unlikely to fit.
