Description
The Archangel AAM1A takes the classic M1A and M14 platform and gives it a modern, adjustable home. Built from ProMag's carbon fiber and glass reinforced polymer, this stock is light at roughly 4.2 pounds, but it feels rock solid in the hands. The precision-fit inlet applies a bit of gentle pressure to the barreled action, and folks who have swapped over from a factory wood or fiberglass stock regularly report noticeably tighter groups downrange. It shrugs off rain, humidity, gun oils, and solvents, so it holds up whether you shoot it at the range or drag it through the field.
What the Archangel M1A Stock Brings to the Bench
The two adjustments are the real draw here. The cheek riser clicks up and down in .05 inch increments with 1.75 inches of total travel, and the length of pull thumbwheel walks from 13.5 inches out to 14.8125 inches. That means you can get behind your optic and keep the same sight picture shot after shot instead of fighting a fixed comb. The gooseneck grip has palm swells on both sides, so it works the same for righties and lefties, and the base has a locking storage compartment for batteries, tools, or small spares.
Mounting Options on the Archangel AAM1A
The forend carries an integrated Picatinny rail with an extended cover, giving you a spot for a light, laser, or bipod adapter. For carry, there are two standard sling swivel studs plus four integral steel inserts that accept push-button quick detach swivels (QD swivels are sold separately). It drops into standard Springfield M1A and M14 rifles, and it will also fit Norinco, Polytech, Armscor, and other M14 variants with minor fitting.
One thing worth knowing going in: this stock is built tight on purpose, since a snug inlet is what helps accuracy. Some rifles slide right in, while others need a little material removed from the trigger pads or receiver area to seat fully. Take your time, follow the ProMag instructions, and a bit of grease on the receiver lugs goes a long way. Made in the USA and backed by a limited lifetime warranty.

Frequently Asked Questions
Will the Archangel AAM1A fit my rifle without gunsmithing?
It is a drop-in design for standard Springfield M1A and M14 rifles, and plenty of people install it with just a screwdriver set and a soft mat. That said, the inlet is intentionally tight for accuracy, so some rifles need a little material shaved from the trigger pads or receiver area to seat fully. A light film of grease on the receiver lugs makes seating much easier. Supermatch models need a pocket cutout for the extra rear recoil lug.
Does the Archangel M1A stock actually improve accuracy?
The precision-fit inlet applies gentle pressure to the barreled action, which helps reduce group size compared to a loose factory stock. Owners moving over from wood or fiberglass stocks commonly report meaningfully tighter groups at 100 yards. Results vary by rifle and how carefully you fit and seat the action.
Can I mount a scope, bipod, or sling to the AAM1A?
Yes. The forend has an integrated Picatinny rail with an extended cover for lights, lasers, or a bipod adapter. For slings, you get two standard swivel studs plus four steel inserts for push-button QD swivels, though the QD swivels themselves are sold separately.
Is the Archangel M1A stock okay for left-handed shooters?
It is. The gooseneck grip has palm swells molded into both sides, so it handles the same whether you are shooting right or left handed. The cheek riser and length of pull adjustments are symmetrical as well.
