Do I need a new BCG?

[enorbit3]

Hey all. So i got myself a CA7 and replaced the upper with a semi auto one. The gun is unfired and all parts are new. This is probably a stupid question, but just want to be sure.

Can i use the Franklin BCG with the new upper i received, so long as I only use it with that upper? If i want to switch back to the non-gas upper, would i need a separate BCG for that?

Thanks in advance.

basically, do i need to have a diff BCG for each uppper on an AR?

You should have no problems using the BCG from your new(ish) CA7 into a new upper. It would be impressive if you caused sufficient wear to cause tolerance issues on a manually actuated AR system

While on active duty, it was stresssed that we should not swap bolts because the bolt and barrel wear together as a system. Same information was passed on during armorer school. With that said, it has been done before, and a limited amount of use "probably" won't result in visible harm. Nonetheless, using the same BCG in two different uppers isn't a good practice. It's silly not to have a dedicated bcg for each upper. I would suggest a new Toolcraft BCG for less than $100. Check out Spice tac. Dave has free shipping and no tax.

thanks, gonna look into spice tac.

Too bad you didn’t get full upper with Bcg included. Buying the ca7 felt like I was just buying a super expensive lower. But I whole heartedly support Franklin for their hard work getting the pistol on the roster. Love those guys

Agreed. Especially considering i have replaced most of the parts on the CA7 lower to get it how I want. But I love Franklin and appreciate what theyre doing.

PSA has them for cheap, more or less constantly.

I last bought one from them for $54.00 a month ago.

Is it as fancy as some others? No. Does it BCG like a BCG should? Yes.

Full disclosure, I bought a nitrided one. Doesn't seem too nitrided to me, at least compared to my other nitrided BCG. But for $54... don't really care.

Just got a toolcraft for $80 off primary arms.

Thanks everyone!

ALL this. Dedicated BCG with EACH rifle always.

It's also a good idea to own a spare. At current prices owning a spare BCG is a must, NiB BCGs under a $100 are around. primaryarms.com is also a good source besides PSA. I keep a spare bolt w/firing pin in my range bag and a couple of complete units in my spares.
