The PWS upper are now forged, allowing for a stronger and lighter product.

A common known fact that has been lost through the marketing efforts of many AR 15 manufacturers is that a forging can produce a piece that is much stronger than a billet part.

As the metal is shaped during the forging process, its internal grain aligns to follow the general shape of the part.

As a result, the grain is continuous throughout the part,giving rise to a part that is stronger, yet lighter, than a billet

Picmod Technology:


The MOD 2 handguard has been equipped with the new PicMod Technology. This allows you to mount any KeyModTM attachment anywhere on your rail while being able to mount most Picatinny accessories directly to the rail in the areas where the PicMod feature is present.

This  gives you the most mounting options without having to use KeyModTM mounted Picatinny rail sections, adding unnecessary width and weight to your rifle.

Adjustable Gas Block:

Position 1 is recommended for for all types of ammunition and conditions when not using a suppressor.

Position 2 is for use with low powered ammunition when using a suppressor.

Position 3 is recommended for normal suppressor use with normal and high powered ammunition.
