Davidson Defense No-Logo AR-15 Ambidextrous Bolt Catch Lower Build Kit, Rare Breed FRT-15L3 Flat Trigger, SB Tactical SBM4 Pistol Stabilizing Brace

The Davidson Defense No-Logo AR-15 Ambidextrous Bolt Catch Lower Build Kit is a lower completion package built around a forged 7075-T6 aluminum lower receiver with a Type III hardcoat anodized finish, no logo branding, and a milled ambidextrous bolt catch slot. The kit includes a KAK Industry AR-15 Lite lower parts kit with a Mil-Spec A2 grip in black, with the standard fire control group replaced by a Rare Breed FRT-15L3 flat trigger forced reset trigger and a 3-position ambidextrous safety selector. The Rare Breed FRT-15L3 flat trigger is a drop-in forced reset trigger constructed from 7075 anodized aluminum and heat-treated 4140 steel, featuring anti-walk trigger pins and a 3-position selector covering Safe, Semi, and Forced Reset. A full-auto compatible bolt carrier group is required for proper function and is not included. The ambidextrous bolt catch kit covers both-side bolt manipulation and release. The buffer system consists of a heavy-duty pistol buffer tube and a Sound Mitigation Buffer H3 at 5.6 oz, which integrates the buffer and recoil spring function into a single self-contained unit. A US Tactical AR-15 M16 Mil-Spec phosphate receiver end plate and an AR-15 carbine castle nut complete the rear hardware. The SB Tactical SBM4 pistol stabilizing brace in black high-strength polymer and flexible elastomer with a fixed design and integral sling slots is included.

No-Logo Lower Receiver and Ambidextrous Bolt Catch

The Davidson Defense No-Logo lower receiver is forged 7075-T6 aluminum with a Type III hardcoat anodized finish and no manufacturer branding, roll marks, or selector markings of any kind beyond legally required serialization. The receiver features a milled ambidextrous bolt catch slot that accommodates the included ambidextrous bolt catch kit. The ambidextrous bolt catch kit provides right and left side bolt manipulation and release, addressing both the awkward cross-body bolt catch access for right-handed shooters and the lack of strong-hand access for left-handed shooters that a standard single-side bolt catch presents.

Rare Breed FRT-15L3 Flat Trigger

The Rare Breed FRT-15L3 flat trigger is a drop-in forced reset trigger with a flat trigger face rather than the curved profile of the standard FRT-15L3. The flat trigger is constructed from 7075 anodized aluminum and heat-treated 4140 steel, featuring anti-walk trigger pins and a 3-position selector covering Safe, Semi, and Forced Reset. The forced reset system mechanically resets the trigger after each shot. The 3-position ambidextrous safety selector provides equal selector access from both sides of the lower receiver. A full-auto compatible bolt carrier group is required for proper function and is not included with this kit.

Buffer System and Rear Hardware

The buffer system includes a heavy-duty pistol buffer tube and a Sound Mitigation Buffer H3 at 5.6 oz, integrating the buffer and recoil spring function into a single self-contained unit. The US Tactical AR-15 M16 Mil-Spec receiver end plate in phosphate finish and the AR-15 carbine castle nut complete the rear hardware. The SB Tactical SBM4 pistol stabilizing brace in black high-strength polymer and flexible elastomer is a fixed non-adjustable design with integral sling slots, pairing with the included pistol buffer tube and covering the rear brace interface for this pistol lower build kit.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. A full-auto compatible bolt carrier group is required for proper Rare Breed FRT-15L3 function and is not included. Verify local and state laws regarding pistol brace use and classification.
