Hello, this is my first post but Iv been lurking here since I got my M4 about 6 months ago. It has been a good resource to find out how I want to upgrade my shotgun but I haven't had any need to post yet.
I ordered a carrier comp tube the same week I got the m4 to begin the wait, then proceeded to break in and get to know the shotgun. I made a couple minor changes once I got a feel for the gun by adding an oversized safety, gg&g bolt release pad, and putting on a field stock.
I looked into 922r parts, and as the geiselle hammer was not available, and I wasn't sure I wanted a surefire m80 rail yet, I went with the freedom fighter tactical trigger and disconnector. I also ordered the 1/2" titanium charging handle.
The FFT parts came in fairly quickly, there was a wait for the charging handle for a couple weeks but my mag tube was still a long way off. When I had it all in my hands I took an evening to put the mag tube and trigger parts in, did some function testing, then went shooting the next week and this is where my problems began.
I shot one 100 round bulk box of Federal target loads from walmart and had an unacceptable number of failures to fire. I would guess around 15%. This is from a gun that has been nothing but reliable for hundreds of rounds so I was more than a little disappointed. All of the ammo did eventually fire on the 2nd or 3rd try.
What do you think is the cause of this? FFT trigger parts? Hard primers on the bulk Federal? Gun lube getting thick and sticky in the cold?
I shoot mostly Federal ammunition and have never had reason to complain. It is consistent and goes bang every time. Did I just get a bad batch?
I will say I am not a fan of FFT. My bolt knob, that I waited weeks for, was almost unusable when I got it. The recesses for the detent were not large enough causing excessive rotation and for it to fall out. I took a file to it and improved the situation but eventually threw it out. This was strike one for FFT and absolutely destroyed my confidence in their products.
I know there may be other causes, it was a cold day and the lube I was using thickened quite a bit. That may have decreased the hammer speed enough to cause the failures. I have cleaned and relubed with a light coating of a thinner oil to see if that has an effect.
I also got a Geiselle hammer as soon as they were available and have already switched out the FFT parts but have not headed out shooting yet as we have had 80" of snow in the past 3 weeks.
I could not be happier with Carriercomp,, I hope kip finds a way to do another run of his bolt knobs this year, the quality of his products are second to none. I am quite pleased that Geiselle has found time to make another batch of hammers too, I know and trust his company to make high quality parts as should be expected for a gun of this price and quality.
