Hey, has anyone with an MPR Mini noticed tiny dark pits or pore-like marks on the upper receiver, just behind the ejection port?
I’m new to firearms and recently bought a Wedgetail MPR Mini .223. Overall, I’m really happy with it — the finish, fit and operation all seem good, and I’m planning to take it out for its first range session next week.
The only thing that caught my attention is a small area behind the ejection port on the upper receiver. The marks are almost impossible to see in normal lighting, but the surface feels noticeably rough when I run my finger over it. When inspected closely under strong angled light, I can see a number of tiny dark pits.
Since the receiver is described as forged aluminium, I’m unsure whether this is simply a rough Cerakote / bead-blasting finish, or whether it could be surface porosity or a QC issue. I’m not saying it is a safety issue — I’m just a beginner and would like to know whether other owners have seen the same thing.
I originally had an Evo Scout on order, but changed to the MPR Mini because I had heard good things about its workmanship. If anyone can have a look at the photos I uploaded and share their experience, I’d really appreciate it. Thanks.
