Needs work.
If you load 20 rounds it will not lock into mag well, take one out and it will lock in. It looks like spring is completely compressed and will not give so it can lock. Will load 20 rounds if you lock the bolt open first
Seating issues
Recently bought these in the 10 round configuration and it does fit the ten perfectly, but the spring does not compress down enough to feed properly unless the bolt is locked to the rear. Besides that it serves its purpose for target practice.

Magazine Doesnt Locked Back Last Rds.
This is not reliable and not consistent. Yesterday at the range brand new out of the bag, doesnt locked back on last round upon inspection, the magazine follower has too much wiggles, too much play. I was using Sig Sauer 125 gr. and Remington 120 gr. Supersonic. I tried using another of the same magazine same thing, doesnt locked back. Finally, I used regular Magpul 556 magazines and had four on hands, every one of the magpul works flawless and has been flawless for many years. D&H, youre going to need to redesign this, guess you paid for what you get is not reliable.
Out of spec
I bought one of each. 10,20,30 rd magazines for my 300blk pistol build. The 20 round would not fit into the magwell. The 10 and 30 had no issues. Upon inspection the 20 rd mag was out of spec. I tried to correct it but the welds were the issue.
