Doing a build. Lower will host 5.56 and 5.45 uppers. Want a nice trigger.
here that hyperfire trigger, w/ its unique mechanism, deliveres a higher energy to pull weight ratio. interested in the hyperfire b/c w/ the one lower hosting 5.45 upper shooting hard russinan mil primers, I want ingnition relaibailty w/ that but dont' watn to have a heavy mil spec trigger w/ heavy hammer spring. Apprecaite any comments of people who have used them or have any relevant thoughts. Thx http://www.tacticallink.com/HiperFire-24C-Competition-Trigger-for-AR15-and-AR10-Rifles-HPT24C.html ETA: I have this mag tactical reciever. The areas where the hammer/trigger pins is re-enforced, thicker, the lower comes w/ a set of extra long but otherwise normal type pins. Does that giessel 3sg or the hypertouch trivver require use of special proprietary pins or could either one be installed w/ normal pins?? I probably need one of these two to reliably ignight the russian mil primers, but I can't go using special hammer trigger pins??? |

I have a buddy who shoots them exclusively in his 3 Gun rifles and I've got to shoot his rifles quite a bit.
While initially I was skeptical of the mechanism and personally I use the Geissele SSA, I can assure you it is a nice trigger and he's not had an issue with any of his after many thousand rounds down range. The one he let me borrow (24, single stage) had pull that was very light, smooth with no wall with a very short reset (reminds me of the HK P7). To quote Stickman from this archived thread: "Phenomenal trigger, it really is that good." |

Quoted: Can you explain that further? Quoted: Quoted: junk just get a wolf spring, file down the end of the bolt for more FP protrusion Yeah... I can't think of a way that would work that would not be either ineffective, a cause of excessive headspace, or just plain dangerous. |

I can't think of a way that would work that would not be either ineffective, a cause of excessive headspace, or just plain dangerous. With $10 extended firing pins from RedX it's not worth doing any more IMO. It does not create a dangerous situation though, it just allows about .010 more penetration into the primer. |

| I never had to resort to using an xtra power trigger spring in my 7.62x39 AR build shooting surplus Yugo M67 but my 5.45 AR wouldn't run 7N6 at all without an xtra power spring. Both builds use PSA single stage trigger parts kits so they're identical otherwise. Both rifles run enhanced firing pins. |

You can find a hammer energy chart at Hiperfire's Resources page.
Don't know how hard Russian primers are, but I've burned *lots* of mil-spec 5.56 ammo, and some Russian commercial ammo (Wolf WPA, Tula) through my HF-24-equipped unit, and never a FTF. And I run the blue toggle springs, which yields the lowest hammer energy. I wouldn't make book on it, but my guess is you'll be fine with the HF of your choice. 
|
| I have the basic Hiperfire 24 in my POF P415... Have had for almost a year now - many, many rounds down range and no FTFs... Absolutely my favorite trigger, very smooth creep to bang bang... You will understand when you run it. Can't go wrong with Hiperfire IMO. |

Quoted: Be careful doing that. Free floating firing and somebody that isn't experienced doing it may get more than a dimpled primer. Quoted: Quoted: Quoted: Yeah...

Quoted: It really won't make a difference, the free floating firing pin already bounces off the primer when the bolt closes. A shaved bolt tail doesn't allow the firing pin to bounce more than it already does, it just allows more protrusion when struck by the hammer. Quoted: Quoted: Quoted: Quoted: Yeah...

Quoted: I hear you. And maybe I am wrong. But I am thinking more momentum with more protrusion. I have never done it myself so wasn't claiming fact. But as with anything if you don't know what you are doing..... Food for thought. Thanks. Quoted: SNIP |
|
Quoted: Momentum is the same. The firing pin is stopped by the primer before it can reach the tail of the shaved bolt, just like it is stopped by the primer on an unshaved bolt. Quoted: Quoted: SNIP |
