M16A1 USGI Armory Upgrade

Armory Upgrade handguards, buttstocks, and pistol grips are created by repairing lightly blemished original USGI M16A1 parts. There are only minor imperfections, resulting in almost brand new looking M16A1 parts. The Collectors Grade buttstock also comes with a USGI aluminum trap door assembly.

Show in the image group below is an Armory Upgrade USGI M16A1 buttstock. The foam core is noticeable on this set and is painted black to match the rest of the buttstock. The New Manufacture buttstock does not have a foam core, as you can see in the picture at the bottom of this page.

M16A1 USGI Armory Upgrade Parts Grades

Collectors Grade: Parts will have almost no blemishes.

Expert Grade: Parts will have very few blemishes.

Sharpshooter Grade: Parts might have small dings here and there and might not be as smooth as the higher grades.

Marksman Grade: Parts will have small dings and scratches and might not be as smooth as the higher grades.

M16A1 USGI New Manufacture

The biggest differences between New Manufacture sets and our other sets are the condition and price. These sets look great but do not have the Original USGI quality.

The New Manufacture buttstock is shown in the image group below. This buttstock has no foam core.  The sling swivel slot is cut out differently for adjustable use of the sling. Additionally, it uses an A2 sling swivel screw instead of the A1.  There is more room to store items but not having the foam core produces a different weight and feel than the other two types of buttstocks.
