Midway has the CMMG upper in stock and on sale for $459. ($240 off)
I absolutely love the one I put on my M&P lower!
The 1st group I shot using the Hornady Black 105gr was under 0.5”. (Edit to add: more like 0.35”) After barrel break-in, nothing has changed.
It also shoots the ELD-VT 80gr load very, very well. Haven’t started reloading for it yet, still making empty brass.
This is my first M-Lok forend and I’m getting spoiled by the slim feel.

Thanks for the notice, KMitch200.

Would you fill in details on your accuracy testing, please?

Shooting was done off bench, 100 yds.
I pulled my scope off of my 308 AR because I didn’t have another cantilever mount. Didn’t bother to bore sight, it was just going to be a barrel break in day. I took aim at a spot on the berm and it hit really close to POA. Aimed at a 2” dirt clod and hit it.
Moved to paper and the 4 shot group (the 1st on paper) was one hole - 1moa down, 1moa right.
Adjusted the scope accordingly and the next 5 shot group was right at 0.5” centered.

Cleaned, shot the ELD-X and it was about 1.5” - same with the ELD-M.
(I am going to try those again on a cooler day.)
The ELD-VT was a nice group IIRC 0.75” but I was having an issue with one of the Stoner mags.
(Returned for replacement, no issues now)

I’ll get out again when it’s below 90°.

I don't see it mentioned, but I must ask if it has an adjustable gas block?

No adjustable gas block…yet.
That’s further down the road for now.

Thanks.
After my one experience with an adjustable block, I like the idea of something that works without having to fiddle with it. I know that may not be feasible with all loads, but I'm willing to stay withing a reasonable range.
