I recently picked up an old Colt .22 conversion kit for the AR15/M16.

Unfortunately, I have no idea how to take apart the BCG to clean.

Does anyone know if there's a site that shows the disassembly procedure for this kit?

TIA

I would just use a toothbrush and a lot of gun scrubber. Don't remember how the FP comes out, but it probably needs to happen occasionally.

I have a 22 conversion from Brownells and the directions advise not to take apart..

There are 2 long screws that are glued in with Loctite. Removing this bond will leave your conversion kit loose no matter how tight you try to tighten these screws.

The firing pin is held in with a roll pin and should not be removed.

Best bet is to use a toothbrush with solvent to remove most of the carbon from the action and chamber adapter. Using a good oil before shooting will help in the clean up process. It's easier to remove loose, oily debris than baked on carbon.

The chamber adapter is soft steel and can be cleaned with a brass wire brush dipped in solvent. You don't want to get too agressive here because you can damage the adapter and cause futher problems. Use just enough pressure to remove the fouling from the adapter. Also be sure to clean the chamber of the mateing barrel completely.

Thanks all for your helpful and informative replies. :)

Brownells has sold Ciener and I understand they currently sell CMMG.

Ciener's literature cautions against disassembly, which is where the Brownells dictum comes from.

The issue is that some folks will bend the rails. Send one back for warranty, and it's obvious that SOMEBODY messed with it, therefore not a warranty issue.

Gently spread the rails and unhook the chamber insert piece from the rail. The bolt will come off the rail and you can clean up the parts with solvent and a toothbrush.

For firing pin or extractor service, drift out the appropriate roll pin.

I got to do this Saturday!
