Hey all,
This thread has slowly become a behemoth lol, and I’m struggling to see which advice is correct so asking the question.
Have a big standard MWS that I’m looking to get more from. I’ve bought the modify tan bucking, six g nub, and an npas from eBay.
What barrel length, and bore should I use to get close to 350 fps? I believe standard length is 250mm, what length can I get in the standard M4?
Thanks
