All good info above. The brownells armorers kits are primarily aimed at / purchased by agency customers who want a one and done solution. It is much easier to fill out one purchase request for an armorer kit rather than filling out a dozen requests for the individual components, likely from different vendors. While that may seem a little lazy, buying one kit from Brownell's also ensures I get the correct items. Mission support and purchasing people will sometimes get creative and procure some interesting things that only vaguely resemble the items requested. Parts is parts, "just as good as"or my personal favorite ,"the pictures look alike".
