Affordable home made AR gas buster charging handle

[Meketrefe]

Who hasn't been on a long competition or shooting session with an AR and got the face filthy.
They sell those gas buster charging handles but they are so-so and they are expensive.
Do you want to make one very efficient and virtually free? Follow the instructions below....

You start with a regular charging handle of your choice.



Get some Fuac approved Silicone that is heat resistant. Gasket sealant is a good one.


Some sandpaper, small dowel or small file will do....





Sand the edges around the joint with the receiver. The glossy anodizing is not a good surface for the silicone to stick to.



Clean the handle well with alcohol, acetone or brake cleaner. All debris should be gone.





You can also apply a small amount on the sides where there is some gas bleeding going on too.






With a swab or paper spread some grease in the receiver in all those contacts points where you do not want any excess
silicone to adhere.



With a little dowel or small plastic strip apply the silicone in the area if some gets under don't worry
just make sure you have some grease on the receiver so it will not stick.

Make sure the silicone goes down and spread evenly and remove any excess. It doesn't have
to be perfect but the nicer it is at this point the easier is to clean up.



Also don't make too much of an edge as this is not needed and there is more risk to tear the seal apart.



Make sure the handle is pulled back and rests there so in the furthest position back there is plenty of good
seal. After you are done cleaning the excess and the area there is very little left to do but to let it cure.


Let it cure for a couple of days and use a very sharp razor to help separate the
seal from the receiver. I will post more on this later if needed.

​This is one I did a few years back and still working. This was one that came a bit
on the large side but it works just fine.




It seals perfectly...



All this can be done in 15 to 20 minutes. Minimal tools and easy as cake.
This is FUAC approved for your compliant or register rifle or carbine.

Please post your tips and tricks.
