The M4A1 Block I also known as the M4A1 SOPMOD was a sister to the US Military’s M4 Carbine. The SOPMOD designation stands for Special Operations Peculiar Modifications and is an accessories system designed in the early 1990’s to customize the base M4 Carbine in-the-field with low-cost off-the-shelf components. This would allow for each set up to be mission specific and allow for proper set mounting of optics, IR/VIS lights, verticals grips, etc.
This TYPE-A M4A1 Block I is built on an accurate Carbine platform with proven mil-spec components to make it an incredibly versatile rifle. The M4A1 Block I is equipped with a 14.5″ Cold Hammer Forged barrel with a TYPE-A ASR Ready Muzzle Brake or other muzzles for an additional cost. Our M4A1 Block I is also equipped with a Knights Armament Quad & CAR 15 style furniture. The TYPE-A M4A1 Block I Rifle is driven by our TYPE-A QPQ bolt carrier group w/R.E.M Polish. Equipped with a DGI (direct gas impingement) system and our new TYPE-A PMC Straight 2-stage trigger to give it consistent reliability time after time.
NOTE: All of our rifles are Hardcoat Anodized and then Cerakoted to give you a longer lasting more durable finish. We wanted your rifle to wear to the anodized surface vs. the raw aluminum surface like some of our competitors. Just another added benefit making our rifles…TYPE-A.
