ohbejuan Posted May 9, 2014 Share Posted May 9, 2014 Maybe I'm too anal about stuff like this, but anyone have any suggestions on what I could/should do about this? Bought an FFT trigger, had someone install it, and it looks like it has some machining marks on the side. Leave alone, return, fine grain sandpaper?

StrangerDanger Posted May 9, 2014 Share Posted May 9, 2014 I'd leave it alone. Sanding it will likely cause more problems since the np3 finish is really thin. Almost all the FFT triggers have these kind of marks in my experience. Todd at FFT would likely hand select you one if you wanted to go thru the trouble.

ohbejuan Posted May 9, 2014 Author Share Posted May 9, 2014 I imagine I probably won't feel it too much as it's too close to the back of the trigger guard to allow my finger to rub too much, but it is bothersome nonetheless on my still-perfect M4 lol. It would certainly be a PITA to replace though. I might just take your advice and leave it alone since I don't feel comfortable replacing it myself Quote Link to comment Share on other sites More sharing options...
Vertigofirearms Posted May 9, 2014 Share Posted May 9, 2014 yup, leave it alone. Having actually used EDM, that should not happen at this process. Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted May 9, 2014 Share Posted May 9, 2014 If you do decide to swap it, I'll do it for free. Quote Link to comment Share on other sites More sharing options...
ohbejuan Posted May 9, 2014 Author Share Posted May 9, 2014 That's really nice of you SD, I very much appreciate it! I'll stew on it for a bit and see what everyone thinks, maybe ask FFT what they think Quote Link to comment Share on other sites More sharing options...
WrenchBender Posted May 9, 2014 Share Posted May 9, 2014 Looks like a casting flaw. I had an FFT in my M4, swapped it out for a Geissele. I was not happy with the way the trigger was getting marred up from the action. The Geissele still looks good. Quote Link to comment Share on other sites More sharing options...
ohbejuan Posted May 9, 2014 Author Share Posted May 9, 2014 FFT said basically don't worry about it, they're sure it's fine...I'll see after shooting it a bit I guess. Not really happy with the way it looks and feels. The reason I went FFT instead of Geissele is that someone posted on here (SD Maybe?) that the Geissele seemed to wear more/faster Quote Link to comment Share on other sites More sharing options...
smeck Posted May 9, 2014 Share Posted May 9, 2014 (edited) There are several threads on this forum relating to FFT issues, none for Geissele. Take from that what you may. Edited May 9, 2014 by smeck Quote Link to comment Share on other sites More sharing options...
WrenchBender Posted May 9, 2014 Share Posted May 9, 2014 I believe that is backwards,.......the FFT wears very quickly. anyone know of the thread about the trigger wear? Quote Link to comment Share on other sites More sharing options...
NHnewbie Posted May 9, 2014 Share Posted May 9, 2014 Am I missing something? Geissele website shows a HAMMER for the M4 but not a trigger. I keep hearing rumors about a Geissele trigger but AFAIK, not yet available. My FFT trigger shows similar marks but they are on a part of the trigger that is not visible when installed.

ohbejuan Posted May 9, 2014 Author Share Posted May 9, 2014 I could be confusing hammer with trigger. I do have the geissele hammer but the fft trigger. I'm not aware of another trigger aside from fft/benelli Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted May 9, 2014 Share Posted May 9, 2014 The casting defects are shown on the trigger. The hammers are made by FFT and Geissele. The FFT and OEM hammers will show deformation after high round counts. None of this has ever been shown to effect function. The trigger shown will not have any functional issues. It's purely a cosmetic defect. Quote Link to comment Share on other sites More sharing options...
12508 Posted May 10, 2014 Share Posted May 10, 2014 (edited) Not to pile on . . . but here is my FFT hammer. It has seen about 30rds. The coating is already peeling off. I don't know what the deal is but it seems extremely weak. The hammer itself doesn't appear to be deforming though. I am going to continue to use it. If it deforms I will get a Geiselle and have a gunsmith stone fit it as out of the box I don't care for them.

WrenchBender Posted May 10, 2014 Share Posted May 10, 2014 My apologies,.........I was completely confused. I started with a FFT hammer and trigger. I replaced the hammer with a Geissele piece. Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted May 10, 2014 Share Posted May 10, 2014 A few hammers compared. The OEM used unit has 12,000 rounds on it. The FFT and Geissele have about 2000-2500 on it each. You can see the deformation where the carrier makes contact with the hammer. The nickel finish on the FFT will flake off on the impact areas.

Unobtanium Posted May 21, 2014 Share Posted May 21, 2014 I have never had an issue with my Geissele parts, in my M4's or my M4S90's. The one time I bought an FFT trigger group, it completely disabled my shotgun. Quote Link to comment Share on other sites More sharing options...
