THE OSA JOURNAL

BUILDS • GEAR • TRAINING • COMPETITION • SHOP TALK

More than a blog. The OSA Journal is where we go deeper into the builds, products, techniques, training and experiences that shape what we do at OceanStateArmory.

OSA
FROM THE SHOP

BUILT FROM EXPERIENCE.
WRITTEN FROM THE SHOP.

The OSA Journal isn't here to recycle product descriptions or repeat what's already been said. It's a place to document projects coming through the shop, break down the parts and ideas behind our builds, share what we're learning through training and competition, and talk about the firearms industry from the perspective of a working custom shop.

JOURNAL
NO CATALOG COPY

REAL PROJECTS. REAL EXPERIENCE.

Some articles will break down a custom build. Others may cover a training class, competition, product, shop project or something happening in the firearms community. The common thread is simple: if we're writing about it, it's because we have something worth saying about it.
