Late last year, SIG SAUER released the MCX-Spear LT to the civilian market. Originally designed for the British SAS. The MCX-Spear LT takes design cues from its big brother the MCX Spear and puts it into a smaller package. Finding and acquiring a new MCX-Spear LT has been a herculean challenge at best. Also, a lot of people just wanted the upper to put on their lower receiver of choice. SIG has answered those consumers’ wants. SIG SAUER is proud to introduce MCX-Spear LT AR Conversion kits. The new kits will be available in 5.56, 7.62x39mm, and .300 BLK.

Below is the product description from the SIG MCX-Spear LT conversion kit chambered in 5.56.

Product Description
