Description
Right here is a True Mil-Spec BCG. Each and every bolt, test fired from the factory. This unit is for builders who prefer tried and true manufacturing and aggressive quality assurance testing over fancy coatings, proprietary profiles and laser engraved logos. AO Precision has provided BCGs to large military contractors such as FN America and large commercial retailers who re-brand and sell these at a considerable mark-up. You can now get these directly from AR15Discounts.com and save big!

Toss a cheap 'filler' in your cart to bump the total above $150.00 - https://ar15discounts.com/products/mil-spec-ar-15-gas-tube-roll-pin/...
For a bit more, this product would compliment the new BCG as well as bumping the total up enough to get free shipping;

I've always considered this seller's flat rate shipping fee to be reasonable.
Wouldn't true mil-spec mean that the bolt carrier is designed to engage the auto sear? This is a neutered bolt carrier.
Is this a rebranded toolcraft?
