Comercial No-Spec

[prepare]

The civilian version of the AR has been plagued with commercial no-spec components;
Colt large pin lowers
Semi-auto BCG's
Semi-auto pocket milled lowers
Aluminum gas blocks
MIM or other inferior alloy parts
Chinese fasteners (YFS gas key screws, chinese gas block screws)
Comercial buffer tubes

The introduction of commercial no-spec components has lead to a lot problems in terms of interchangeability was well as just plain inferior and cheaply made no-spec components.

While there are a few enhancements and improvements over genuine mil-spec it is now possible to have a nearly all mil-spec carbine with the exception of the FCG.

What you get with mil-spec is what Mike Mihalski at SOLGW refers to as "predictability of performance". Meaning wear items and service life are reliably predictable vs unknown.

So don't knowingly buy inferior and/or unknown items. Stick to known producers of quality products.

Lol. Is that established bar for the o/u? Might as well bring Colt and the TDP into fold and shoot for 25 pages full of hate and discontent.

Don't forget to mention those non-compliant roll pins!!

One of the points of the post is that it has taken many years for a true mil-spec AR (minus FCG) to be available/accessible.

I am not sure I see if there is a point to this post. Ues there are sh!tty parta out there..... and many are "MIL-SPEC". Don't get too wrapped around the whole mil-spec thing......

DON'T BUY CRAP AND YOU WILL BE OK.

As Mike at SOLGW says, this isn't common knowledge for industry outsiders.

Not entirely true.

For the longest time the only place to get AR parts was from Colt's or surplus military parts, both I would say are "true mil-spec". Only in the last 14 years has this changed.

I only began the deep dive into the minutia a few years ago and I don't have an engineering background. Just an interest for the details and a few reference books. I just recently got Black Rifle by Blake Stevens!

Weren't the early Colt AR 15's large pin lowers with semi auto carriers?

No.

Those were short lived products from around 1991 to 2005.
