I just picked up my Centurion Arms lower receiver and rail from my FFL.
My reason for buying this lower was that I am in the process of converting all my ‘no name lowers’ on rifles I’m keeping to lowers with cool logos and recognized by most as seemingly legit. My only complaint is that the Centurion Arms logo was more understated than I figured it would be.
The lower is blemish free, with clear selector markings on both sides. Otherwise it not cluttered with markings that aren’t required. The Centurion stylized arrow and the CM4 below it will lok nice with the simple goldish fill I have envisioned.
The rail, likewise, is blemish free, with the Centurion Arms logo laser engraved in white on both sides of the rail. My wife thinks I should do the fill on the receiver in white to match, jury is still out on that.
I know this is a sparse report, I’m going riding tonight and won’t be able to assemble the lower and upper until the weekend. This one will have a Stag LPK with a Toolcraft C158 bolt, and a Sionics 16" LW mid-length barrel.
An additional detail just reared its ugly head - I have several Geissele gas blocks of the .750 persuasion standing-by, but no .625 gas blocks - so it will be a week or so, I guess.
Anyways, just wanted to reassure those of you who maybe haven’t received them yet, they are, in my eyes, GTG!
They removed material probably due to fitment/measurement spec. I hit it with a micrometer and it’s about 1/100 thinner on the bare metal side. Hopefully re-anodizing will still allow upper to fit.
Me too. The upper and rail were both fine, but I got two blem lowers, one worse then the other. No issues with roll marks or engravings though. They’re out this week on holiday so I’m sure they’ll make it right next week. I’ve worked with them before and received great customer service, so I’m not worried, or in a hurry, and I’m still excited about the new parts.
I am in same boat as you. Both lowers and rail have cosmetic issues as well. The upper seems to be ok. I emailed them also. Was staying quite until others posted Incase I was an isolated incident. Spoke with one other board member and he confirmed having same issues in same areas as ours. Am disappointed in them.
Edit: Mine are not bare like yours, they appear to have been touched up with something in an attempt to seal the surface. The only bare metal I see is the bolt catch spring hole. But these are blems in my opinion. Will I use them, most likely. Will I keep them for my kids as originally planned, no. Shame too since they are consecutively serial numbered.
My lower had a slight blemish on the inside edge where it meets the upper where you could see shiny aluminum. It also had some burs from when the bolt catch roll pin hole was made, as seen in the photo below.
The burs were easy enough to take care of, and the other blemish was inconsequential. Overall I’m very happy with the upper and the service from Centurion.
BCM is who made the .625 gas blocks I’ve been using. I just picked up one from Cross Machine Tool of the same size which looks good but has not been used yet.
You received it with bare metal inside? Seems odd. I assembled a few lowers today that had machine work done after anodizing. Internal stuff isn’t an issue, but external areas or area with moving parts are a different matter to me.
(Not being a smartass but wanting to make sure I’m understanding you) Is “machine work done after anondizing” that you experienced different than the pic of bare metal I posted? I figured thats exactly what they did to my lower, machined to get in spec post anondizing.
Happy to have participated in this cool event anyways. I am along some of the other comments: I will most likely still use it for as planned, but I am not as impressed as, I felt, I would have been without what’s pictured below.
I love the Logo, the depth of the imprint, all looks wonderful except that spot milled after anodizing.
ETA: I want to include, to the picture posted above, your milling looks pretty clean. This one still has the shavings, cutting oil, etc. This is as arrived. My wife and I had an appointment, so I just took it out of the box, gave it a quick look over, noticed the milled out spot, wrapped it back up and stuffed it away until today. But, that’s only been a few days.
