HyperFire Trigger potential issue with non-rotating trigger/hammer pin

Having recently fitted a non-rotating trigger/hammer pin set I discovered a fairly serious safety issue. Because of the way the HyperFire trigger works, there is very little energy from the springs at the point of the sear separating. Badly made (I won't mention China because China is where Vortex products are made) trigger/hammer pins which are too short result in the wall of the lower being pulled in by the tightening of the screws into the pins. This causes extra fiction on the hammer which is enough to stop the hammer moving beyond the counteracting springs on the HyperFire. The hammer is released but does not have the force to go forward. If there is a round in the chamber, this is potentially a lethal scenario as a slight knock to the rifle could be enough to dislodge the hammer resulting in an unexpected discharge.

NOTE: this is less likely to be an issue if the pins have a screw at only one end.

This is in no way meant to be criticism of the HyperFire trigger - mine is brilliant I have no intention of changing it.

  1. OK, not what I was expecting, but was actually more fun. More shooting than I expected but can get expensive.

    • Thanks Andy, unfortunately shooting can get expensive. However, you have to remember that shooting with us saves costs you may have if you shoot with a club. You don’t need a licence, insurance, medical checks or (biggest saving) your own guns. Even if you had a licence, you would find it hard to get a MP5, AR15, AK47, Sig Uzi because they are all considered to “be the same” in the eyes of the law. Yes, our ammunition is quite expensive, but that’s to cover our costs (unless you shoot thouss of rounds a year) is cheaper than having your own equipment.

  2. Many thanks from us both for a very enjoyable time at your opening this afternoon. Excellent emphasis on safety; excellent variety of rifles, styles advice.
    We hope you’ll be holding more instructional events in the near future. Please keep us informed.

  3. Really enjoyed the session it was great fun! Clear instructions lots of information given about the different guns. Staff very informative helpful for myself being inexperienced. Worth every penny. 100% will go again I look forward to it!

  4. I thoroughly enjoyed it I had a great time. I have never done anything like this before I now want to go again. There is a wide range of guns you have the opportunity to shoot I was shown clearly safely to use them. Thank you for the experience I hope to come back soon!
