I’ve always felt I had to match receivers , dont know why. Also like my buffer tube to be the same brand. This sums it up:
I don’t have any guns to match receivers but if you ever seen my shop walls, you’d know I have OCD.
wait what, we’re not supposed to mix/match AR’s ?
I’m trying to change my ways but mismatching receivers really gets to me. I feel like monk when I see it.
It’s never really bothered me, but I do try to purchase the same brand upper at the same time as the lower.
Most of the time it works out, because I have a build plan in mind and it’s a matter of convenience to buy those two parts at the same time. However, I have a few lowers laying around I bought when prices were good that don’t have any upper or immediate plans for a build.
AR-15’s I have no problem mixing and matching, never been an issue. The large frame AR’s is a different story, I will never mix brands, almost always causes issues, functional and aesthetics.
I’m limited it experience about this but my thoughts are if it is built to a certain set of specifications than mix-and-match should be OK as far as uppers and lowers go. It has worked for me so far.
Same here. My most recent build was a Aero Precision M4E1 lower with Palmetto State premium upper and Bravo Company BCG. It runs great, so the logos are irrelevant to me.
If you stick with quality parts, it will run smooth and be reliable.
I used an Omni hybrid lower because it was the only ar lower left in the store at
The time and it matched up to a PSA upper just fine. I had heard stories about the hybrid lowers not matching up but it went together beautifully for me.
My thoughts as well for the AR 15 platform.
So basically im weird, didnt need reassurance on that but ok.
Long before the topic of firearms was discussed…
I’ll mix/match anything as long as it’s quality.
Done with the junk/cheap crap…learned my lessons there.
Ummmm……Isn’t that the whole concept of Mil-spec.? All true mil spec receivers, uppers, and parts ought to interchange.
While true among the “better” non custom brands, there is still sometimes an issue with tolerance stacking (2 brands within mil spec but at different ends of the specification). Also fits and finishes, markings etc…really for me the issue is I like to match them, much like a woman with clothes or a little girl with barbies.
We just mill what does not fit.
