Kral Arms Quick, cheap power upgrades

[thammer]

Seems lately I'm getting several Kral questions again. Here's a quick cheap trick to add some power. The trick is cheap but you need expensive tools or to make a friend with someone that has them... lol

Tap the valve 1/4x20 at the valve stem exit. Epoxy in a 1/4x20x3/8ths brass screw. Turn the head down flush with the rear of the valve and drill a new hole to match a QB78/Gauntlet or equivalent smaller diameter stem. Shorten it to match the factory length and a reduced size poppet from Delrin or Peek. Adds a larger flow of air for a quick short pulse.

Nice trick. I like it. I’ve been tempted to jump onto a Kral but really don’t need any new rifles as this time.

Nice cheat! Lol I take it the same could be said for reximex guns? They seem to have the same bottle valve.

Works for many rifles Reximex included.

The trick works for most any rifle. Even regulated guns. If it uses a valve stem, poppet, and return spring this can be applied.
