tyler2you Posted October 13, 2017 Share Posted October 13, 2017 I can confirm the Wilson FP works perfectly in the Taccom Bolt. Shot a match last night and it worked as expected. Hoping it will last a lot longer than the original. Link to comment
TRUBL Posted October 13, 2017 Share Posted October 13, 2017 In answer to triggers.......the std JP trigger if you install correctly is pretty much bullet proof and better than any hiperfire. I run hiperfire in my rifle......until I can swap it out for the JP. And yes.....seems like the hiperfire hits the 9mm firing pin a little hard. Link to comment

What about using the lower power springs included with hiperfire trigger? Will not help with not damaging firing pins? Link to comment

Patrick Scott Posted October 13, 2017 Share Posted October 13, 2017 But but, us shooters wont go to a heavier trigger just to save firing pins. lol Link to comment

Inspection of the firing pin indicated very slight mushrooming of the firing pin but not enough to be concerned. This firing pin has over 7000 rds on it all from a Hiperfire 24c with heavy springs (lightest trigger pull). Maybe I should buy a lottery ticket. Link to comment
nickbfishn Posted October 13, 2017 Share Posted October 13, 2017 Update… I got my new firing pins and retaining pin from FedEx Today. Took it to the range and fired 150 rounds with no problem. Looks like I will be able to shoot my match tomorrow after all :-) But for those of you on the fence do yourself a favor and go ahead and place an order for a back up firing pin, or two. I ordered 3 CMMG Stainless steel pans from primary arms at $11.99 Link to comment
Southpaw Posted October 17, 2017 Share Posted October 17, 2017 I haven't broken a firing pin yet, but I found this while cleaning my PCC recently. It might be hard to tell from the pics, but a good portion of the firing pin tip is either dented in or worn down and the back of the firing pin is mushroomed out (new one is on the right). This is with under 2k rounds through it using a Geissele G2S trigger. Anyone else ever see this kind of wear on a firing pin tip? I did replace the firing pin when I saw this, but kind of curious how much longer it would last Link to comment
wyliearms Posted October 18, 2017 Share Posted October 18, 2017 I have one right now that has all but eliminated this issue. After a few more 1000 rounds, I will be ready to advertise it. Hold tight. It needs to be proven more first. Link to comment
BlackBuzzard Posted October 19, 2017 Share Posted October 19, 2017 (edited) My JP FP broke today during 350 rounds of practice (maybe 6000 rounds total on this factory new gun). Discovered this while cleaning after range session. I believe the gun fired many times with a broken FP! Its possible the FP broke on the very last round of the day, but I doubt it. So the GMR15 never failed to fire even with a broken pin. Edited October 19, 2017 by BlackBuzzard Link to comment

BartCarter Posted October 24, 2017 Share Posted October 24, 2017 (edited) OK, haven't broken a firing pin yet, but I just closely inspected the firing pin in my CMMG bolt at about 3,000 rounds. The firing pin tip looks like it has been beaten up a bit. The shoulder at the end of the firing pin tip looks like it has been hitting on part of the inside of the bolt, causing a ridge to form. The back of the firing pin has a slight mushroom. I replaced with the spare I keep on hand. Maybe firing pins should be replaced as a normal maintenance. POF 4.5 lb trigger.

Bullet56A Posted October 24, 2017 Share Posted October 24, 2017 Gotta PSA no broken pin yet. No dry firing to speak of. 3k with Hiperfire 24c 7k with stock w/JP springs. 10k and rolling along smoothly. Pin is getting mushroomed from hammer strike. Link to comment

They all have a shoulder that does not have a nice big radius and that is where they break. Thanks, Eric My stock Olympic Arms 9 uses a .223 firing pin. It is tapered where others have a sharp shoulder. Gun is about 10 years old. A bazillion rds. Never have replaced the pin. 3lb Timney trigger. Finding reliable Sten mags are the gun,s only problem.

But my tip was not as degraded and the shoulder was not as worn - there was still most of the taper left. Looks like yours has the taper worn away (by striking the bolt?). Link to comment
Southpaw Posted October 24, 2017 Share Posted October 24, 2017 Yeah mine does look like the damage was done from hitting the inside of the firing pin channel, but I'm not sure if that's really the case. Link to comment

bladewurk Posted November 18, 2017 Share Posted November 18, 2017 I have an Adco ramped old style RRA bolt with about 3000 rounds thru and no breaks, but it does look beat up. I have a standard FCG, standard hammer with JP Hammer spring. A spare FP is on order JIC Link to comment
L9X25 Posted November 18, 2017 Share Posted November 18, 2017 One of the local guys with a JP-13 had a light hit during last month's match and discovered a broken firing pin after the match. It continued to fire but he suspected something was wrong. He also has a Hiperfire trigger in his rifle. Link to comment
Old3GNR Posted November 18, 2017 Share Posted November 18, 2017 Just a data point. My JP GMR-13 now has about 5000 rounds through it and after reading about these failures, I pulled out the FP and it looks new. Link to comment
