    These caps thread in fine but not very far. Will need a longer spring and/or extra cup to take up the distance the caps don't.

    These solvent traps are solid, well made, and solid. They work awesome on my 30 cal rifles. I have recommended these to,a,handfullmof my friends. Work perfect. Next time I'll go with titanium for weight.

    Superb product and workmanship. However, the USPS delivered the package late and bearing evidence of tampering. It looked forcibly open and with a delivery address label faded as if inmensed in water for a while or washed away in an attempt to hide evidence... Cutious...
