You can probably find cheaper, but you’ll get what you pay for.

Now that it’s become old news, some people are surprised to receive older v1.0 parts. I’m not throwing them away… I’m phasing in the v1.2 as the v1.0 runs out.

Stainless Adapters have a medium-grey, uniform, matte finish. Much darker than the stock photo above suggests.

The Parkerized adapters are single-point turned from billet 4140 Chromium-Molybdenum Steel (not Aluminum or low-carbon steel). Please note that Parkerizing color and consistency are directly related to the metal surface and cannot be completely controlled. It’s a minor trade-off for the superior protection and durability.

This is an evolution of the Solvent Trap Adapter, and is, in fact, no longer a Solvent Trap. It is a pass-through solvent recycling and cleaning system. Replacement filter cartridges are available as low as 7 microns! I just stuff it full of rags/paper towels/toilet paper. This makes all other rifle-platform adapters obsolete. Small bore/non-gas-op/handguns might still prefer the older style.

NOTICE: When you receive your Parkerized adapter, be sure to give it some oil. It will be thirsty! This is very important because the corrosion resistance of Parkerized materials is dependent upon the micro-crystalline structure sponging-up oil. WD-40 makes an excellent anhydrous initiator, and you probably already have some. Eventually, a proper oil would be preferred.

These have wrench flats for a 13/16 crescent wrench.
