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.

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 Mil-Spec heavy-duty 6-position carbine 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 Magpul DT adjustable carbine stock in black reinforced polymer is included, with a collapsed length of pull of 10.5 inches, an extended length of pull of 13.8 inches, a 3.3-inch adjustment range, an overall stock length of 7.0 inches, an overall stock height of 5.3 inches, a weight of 9.8 oz, and integrated sling attachment points.

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 Mil-Spec heavy-duty 6-position carbine 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 Magpul DT adjustable carbine stock in black reinforced polymer provides a 3.3-inch length of pull adjustment range from 10.5 inches collapsed to 13.8 inches extended. The overall stock length is 7.0 inches, overall height is 5.3 inches, and the stock weighs 9.8 oz. Integrated sling attachment points are included. It pairs with the included Mil-Spec carbine buffer tube and covers the rear stock interface for this 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.
