For what it's worth, I bought my M10X-Z for just under $2000 on June 1 2020. I was super stoked since this would now be the most valuable piece in my growing collection.
I took it out the following day to see only pure disappointment.
The entire day I got no more than 40 rounds out
First few rounds were so stiff to charge and feed
Every other round would lock the bolt forward so only excessive force or mortaring would pull it back
After a couple test fires I was willing to give benefit of the doubt amd let it break in.
I continued to experience FTEject and FTF at a ratio of 1 decent shot to every 5 rd
Eventually my chatging handle popped out while shooting (Yes it was spring facing upwards and rotated to lock upwards)
Finally on about round 35 or so, the bolt was locked once again, this time however, it was the last rounf in mag that was fired, but last round hold open failed to hold bolt carrier back and it closed forward on empty casing, lodging it into the barrel
Average picks were no match so I packed up for the day
Once home I tapped a cleaning rod through the barrel and was able to get the spent casing out.
Immediately sent M+M a message and still waiting
Meantime I have cleaned, lubed, and wiped off any excess.
I have tried racking new rounds but continue to experience FTF and FTEject. The bolt occasionally closes with roughly 1 inch of space, and requires mortaring to open.
For $2000, I dont think these are problems I should be facing in the first 30 rounds.
Break in I get, but how am I to break in if it doesn't operate?
Waiting for reply from M+M, may take out to test once more after fresh clean and lube, dont expect a whole lot since Im still experience the bolt locking to the cartidge.
If anyone has any ideas or thoughts please let me know, I would really like to enjoy this rifle.
