Can you post a picture of your PROBLEM PIN?!?!
Can you post a picture of your PROBLEM PIN?!?!
Well, here's the problem. As I stated above I have had this problem with four different BCGs in my three ARs. I manage to get them in eventually, but it ends up being like 2 monkeys f&#king a football. I struggle and struggle and struggle with it but get it eventually. Just something small but important that I am missing.
Does the above offend? If you have paid to be here, you can click here to put it in context.
That’s honestly incredible.
OP, I’ve had one or two pins that were a pain in the ass. Usually a little twisting or pressure is one direction is enough to catch both of the legs and slide into the far side hole. There is a chance that you just have several pins that are far more spread than they need to be which, again, can be replaced for literal dollars.
Well, I don't clean my guns a lot... but the other day I cleaned my SBR because I was shooting prone and quite a bit of dust was flying around. For the first time, I had a short challenge getting that pin in. Seems like it was splayed out a bit so I pinched it together and it finally went in.
Regarding cleaning. I clean my guns probably about every 1500 rounds and use Lucas extreme gun oil (think thats what it's called). I know some types of guns need to be cleaned more. But I shoot high quality AR's and Glocks. They don't need a lot of attention. A few years ago Frank Proctor had a BCM he just kept lubed with Lucas and at that point he had about 40,000 rounds without cleaning it.

The video in Post 3 has a good technique for reinserting firing pin retaining pins that have their leg spread further apart than is typical. Pull out one of your BCGs and give it a try. If that still doesn’t work and all your pins are like that just buy new pins. BCM sells firing pin retaining pins for $1.35 each. Brownells has a bunch ranging from $1.19 to $3.99 each depending on brand. Buy a replacement pin for each of your four BCGs and you won’t have to deal with your wonky pins anymore.

My suggestion the OP is to buy a spare BCG and a few extra pins.
Practice disassembling the spare BCG where there’s no stress to get your rifle back together and once you’ve gotten that bug out of your head you’ll have a spare BCG in case one of your others goes TU.
(Or to build a new rifle around as often happens with loose AR parts)
Are you sure the firing pin is in the proper position when reinserting the retaining pin? Like, is the firing pin flange blocking the hole?
