Over at Guns & Coffee, Fred’s buddy MacGyver fell victim to a broken extractor spring on his AR-15 bolt when they were at the range.

His friend, who is an Army Engineer Officer came up with this fix:

Yes that’s a rubber band, and it worked. Awesome.

The AR-15 works perfectly fine in wet environment such as a shower.  No modifications required.

Here is one such example:

Because you can never be too prepared…

The vacuum sealed bag is not needed.  A stock Glock will work perfectly well when wet!

If you are planning on being in very wet environments often though it is recommended to swap your regular spring cups (recommended only for use on 9mm Glock models) for special “maritime spring cups”.  This allows water to more freely pass by the firing pin within the firing pin channel.  Having regular spring cups in might hinder the drainage of water and create a hydraulic force within the firing pin channel which in turn would slow the firing pin down enough to cause an FTF (Fail To Fire) because of a light primer strike.

Maritime spring cups (notice the channels it creates, where water can drain):
