Yes, absolutely.

Hi Leon and welcome. Yes Sir it is a quality "Forged" Lower and will hold the Rare Breed reset product without issue. This complete lower receiver assembly is meticulously crafted from a 7075-T6 aluminum forging for maximum durability. It features a generous mil-spec type III class 2 hard coat anodized finish, providing incredible protection against the elements and heavy use. This unit comes fully equipped with the Spikes Tactical Pro Pistol Grip, a standard M4 carbine collapsible stock, and a reliable 6-position mil-spec buffer tube. Cheers, stay safe and enjoy!

Hi Leon, yes, the Spike Tactical MK4 is considered to meet or exceed mil-spec standards. It is made with materials and finishes that align with military specifications. The Spikes Tactical MK4 lower can accept a Rare Breed trigger. Stay safe & have a great day!

Yes, Spike's Tactical lowers (including those featured on their M4 LE and various builder sets) are built to MIL-SPEC standards. They are forged from 7075-T6 aluminum, feature a Type III Hardcoat Anodized finish, and typically use a "low shelf" design, which makes them generally compatible with aftermarket, drop-in trigger systems, including those requiring more space like the Rare Breed FRT-15.

Good morning to you!! Yes the Spikes Tactical Mk4 is milspec and will hold the rare breed reset product. Hope this helps. Have a good rest of your day. 🇺🇸🇺🇸 'Merica' 🇺🇸🇺🇸

Why yes the Spikes Tactical Mk4 is a milspec lower receiver. It is made from 7075-T6 aluminum forgings. Buttstock, milspec buffer tube and buffer tube.

Yes, the standard Spike's Tactical lower receivers (often referred to as ST-15, Spider, or M4 LE) are manufactured to MIL-SPEC (Military Specification) dimensions. They are forged from 7075-T6 aluminum, feature a "low shelf" for RDIAS (Registered Drop-In Auto Sear) compatibility, and use standard MIL-SPEC fire control groups. Regarding the Rare Breed FRT (Forced Reset Trigger) product: Fit: Because the Spike's Tactical lower is built to true MIL-SPEC standards, it is physically compatible with the Rare Breed FRT-15, as the trigger requires standard AR-15 trigger pin locations and internal dimensions. Function: Users have reported successful installation and function of the Rare Breed FRT in Spike's Tactical lowers.
