Grendel vie six8 recivers

[A5BLASTER]

Yes for your rounds that your able to move the coal out more than what you could use in a standard grendel mag? Is this to attain higher velocity or to be able to use heavier bullets? I find your research/work on all of this interesting. I wasn't sure how much if any speed gain.

Thx for all the info you've posted on this.

My CPD/duramags allow the same coal length as these mags.

As to any extra speed I really haven't payed attention to see what I am getting compared to others.

Now I do have one of the mags I windowed that I can load much longer loads in but that's only usable with the 129 ablr bullets.

I have been doing more testing to get the mags to hold and function with 30 rounds then I have been doing load work.

Will return too doing load work soon.
