Good choice. You won't regret it. Personally, I think it even looks better. I am so glad I switched to the field stock. It feels better it looks better it shoots better.
I had the fixed pistol grip on my M4 when I first got it. Hated it. I put the Field stock on and absolutely love it. It feels great and even though the numbers are the same the field stock feels much shorter than the fixed pg stock and shoots much better.
I didnt like the size of the 3/4. The 1/2 looks much better as well imo than the 3/4. The GGG is also a good brand but I just like the FFT more. The material, fit and finish as well as the customer service is all top notch.
I have the FFT charging handle and bolt release, and they are amazing in build and quality. I have had zero issues with either of them, and I run my M4 hard. I have the 1/2 charging handle and have had no problems with it. I highly recommend the FFT over the others.
I have the 1/2 and have had zero issues like this. I run my M4 a lot and have no marks on my receiver. This is an old thread so maybe he has changed something on them. I love FFT and their products and have always done good by me.
