I have a few different lowers,all assembled with colt or CMT parts kits and on a couple, the reciever push pins are extremely easy to dis engage. Like the detents arent deep enough or the springs arent strong enough.
Not that I want to have to use tools to take my gun apart for a field strip but I do like them to be engaged untill I take them apart deliberately.
Any of you guys had that issue?
What did you do, if anything, to resolve it?
A stronger buffer spring will make the push pins harder to push out.
I like the pins to be fairly tight too, not get the ballpeen and the drift punch tight, but a fair amount of thumb pressure tight.
Try replacing the takedown and pivot pin assemblies with another brand.
I have had pretty good luck with J.P. Dewey takedown and pivot pins, DPMS detents, and Brownell springs.
Tight, but not too tight, set-up.
All this stuff can be aquired from Brownells.

Never had this problem, so just looking for an answer…
Are the pins fitting properly in the lower, I.e., too much play?
Are the detent springs fresh, or worn? (You might try some High Power springs.)
You’ll get some conflicting opinions on this, but I use an Accu- Wedge because I like the feeling of a tight upper/ lower feel, and IF trimmed properly will not interfere with the BCG during recoil. Mine last over 7,000 rounds.
Detent spring?
My Colts and Bushy pins were pretty easy to push out.
My Stag was almost impossible, I have to use a tool to push it out.
When I added an LMT SOPMOD to my lower it made the pins harder to push when the upper is attached. I added a completely new tube and buffer, and what looks like a longer buffer tube spring.
The lower’s pins are also hard to push out when I move it to another upper. If the lower is by itself, they are easy to push out.
So… I figured the longer buffer tube spring is making the pins harder to push out when an upper is attached?
