Thanks for the heads up I think my next build I will piece It together with a matched upper and lower set. I found a ton of useful information here just in a short amount of time. Like I hadn't the slightest clue it would be so finicky about what works and doesn't compared to the ar15 platform.

Appreciate the tips. Like I said, first time with this build it's kind of crazy how tiny things get in the way.

After finally having the time to disassemble the upper and clean it and apply some lube it finally goes back far enough for the bolt catch. Not sure what changed there wasn't any wear marks on the bcg or upper receiver as if it was binding. Will comment again after barrel break in if it ends up doing the same thing.

Update after measuring everything it's 30 coils 11 3/4 length it's a short buffer , the ID is 7inch . I removed both the spring and buffer and it barely pulls back far enough for the bolt catch to lock in. And I mean barely I have to force it back pretty good. I put the buffer and spring back in. I noticed when I was trying to cycle it this morning it acted like it was hitting the buffer tube instead of going in so it wouldn't move the BCG at all. With the spring and buffer removed the BCG goes in 3/4 the way and feels tight so I may have a an issue with the buffer tube it's self or the bcg is milled slightly too large. Any thoughts?

I believe I had seen your dissatisfaction on another post. Again don't really care about brands at the moment it was a cheap build. I am more or less interested in the functional issue if anyone has had a similar issue , it is still under their warranty as I just received it. If its a flaw with the BCG being out of spec or something I can just send it back.

Now before the trolls and hate begin to rain down on me.. these are the parts I am having issues with. PSA10 Gen3 lower BCA 18" side charge upper My sad discovery after opening the upper and placing it ever so joyfully on the lower , function checking the BCG to the rear ..... off slips my hand from the charge handle. 2nd attempt to pull BCG to rear , it doesn't move at all. (this happen a few times) last attempt I reseat the upper and lower and it pulls back 3/4 the way only to stop again , at this point its clear of the FCG and the bolt release but will not pull back to lock. I don't currently have the photos to show it but there is a good 1 inch of slide space from where the BCG refuses to pull back and the upper housing. I cannot think of anything that would keep this from happening other than the BCG is out of spec and is catching on something. Before I fire this thing and rip a hole in the upper or destroy the rifle completely I'd like to know if there is anyone out there that can think of something to try. I have owned and built several ar15's but this is my first 10 build. to note I wasn't worried about having the most awesome parts. I have 5 acres an a pretty decent hog issue from the cattle land next to me and the deer feeders on the land behind me. this was built just as a cheapo plinker. Thank you in advance, I hope out there in internet land someone may have some enlightenment for me (besides don't buy BCA because I'm not worried about a SHTF issue with this build)
