Ok so I'm going to go ahead and drop the ball now even though I haven't finished testing yet.
Not to long back I seen a post on anouther site where someone had put a Larue upper on a six8 lower and had it running grendel from the 20 round mags he had.
So I ordered up a set of recivers and some 10 round and 30 round mags and got too testing.
So here goes.
First I tested the 10 round mags.
They will hold and feed 9 rounds of grendel straight out the pack. There is a limiter built into the spring retaining plate they I cut down to allow the mag too hold 10 rounds.
The mag will hold 10 rounds of grendel but is a lil harder too seat. But with that it isn't reliable. One mag will feed fine but my other has trouble feeding the first round every time.
So if loaded with 9 rounds of grendel it seats easly and loads perfectly every time. It will also seat just fine with 9 rounds in the mag on a closed bolt.
I also windowed one mag just to see what kind of coal length it would give me and it comes out too 2.350 coal length that I can load too with the mag windowed. If someone try's this don't damage the over insertion tab. If the tab is damaged are removed it makes the mag completely useless.
So on too the 30 round mag. The 30 round mag will hold 29 rounds of grendel. But I could not get it too feed more then 26 rpunds. The issue at 26 rounds is you can't leave the mag inserted in the rifle for long periods of time. If you do it causes follower binding and the top 5 to 7 rounds get real lose in the mag and stop feeding.
So I dropped down to 24 rounds. The mag seated nicely and feed properly but again if leavt inserted in the rifle for long periods of time, it would have the same issue's it had when loaded with 26 rounds.
So I moved on and dropped down too 20 rounds and ding, ding,ding winner, winner chicken dinner. It loads fine and seats easly and feeds perfectly and doesn't have the follower binding issue I had before when loaded with more rounds and leavt the mag inserted in the rifle.
I have some 20 round mags inbound soon to test but I'm confident that they will work just fine loaded full with grendel.
The 30 rounds work great loaded with 20 rounds of grendel but if though the 20 round mags cost more I would rather have the shorter 20 round mag holding 20 rounds then the 30 round mag holding 20 rounds.
On too the recivers.
The fit is super tight and the recivers are well made. I don't know what Lwrci coats their recivers with but God dang it is a pain in the butt too break them in. Most ar15 sets I have broke in only took maybe 100 too 200 cycles. These six8 recivers took close too 400 cycles to get them nice and broke in and smoothed out.
A side point I forgot above about the mags. The springs in these mags are without a doubt the stiffest dang mag springs I have ever dealt with in my life. Like 2x stiffer then the elander grendel mag springs.
Ok back to the recivers. They came with ambi controls. In short I hate them, they just cause drag and slow down the action and make it harder to seat mags. I guess I could see the use of such things in a combat situation or for the mall ninja crowd. But for me they are just junk, regular single controls are just perfect.
I will post some pics soon.
So there it is fellas. Lil data point for guys to think about. Not saying everybody should do this. Just wanted too do it and see what I could shake out.
I'm going to go out and say this now. If you read this post and your first thought is too bump your gums and post stupid options based on your feelings or whatever. Just keep your words too yourself. I don't want this turning into a stupid argument or third leg measuring contest. Take it for what it is a data point that the grendel community didn't have before today.
Enjoy fellas, pics coming soon, hopefully someone can help me post them since my pics always come out small and hard too tell what it is. Sneakyone where you at bro?
