Hello,
New to m4. I purchased the freedom fighter tactical 3/4" np3 coated. I like everything about it, but... it does not stay in quite as tight. I'm not sure if the detent will keep it in always, but it's definitely easier to pull out. This might be due to the extra leverage given the size.
The thing I haven't seen commented on anywhere else is that mine touches the side of the shotgun at times. There is a slight amount of play in the bolt as there is with the oem bolt. However, if I push in on the fft made bolt, the bottom of the larger diameter of the cylinder touches the side of the gun. The oem has a smaller bolt handle diameter and does not touch as it is not large enough to reach. In addition, if you look at the fft bolt, you will see that it is a 90 degree cut from the narrower bolt to the larger cylinder. The oem has a slight bevel. I recommend that you include a bevel as well or be sure to make the bolt a little longer before the larger cylinder is attached to assure it doesn't touch due to small tolerances in gun mfg. I called into freedom fighter and he said the bolt probably goes in slightly more on mine. He offered to send it back and was very nice, but why not have a design that prevents this issue. I purchased my gun brand new, so off the shelf should work. A better design to prevent this would be to make it longer or include a bevel which would also shave a little weight.
I really hope you make a better one as I like the larger size diameter bolt.
Any update?
