My 6.5 G Side Charger

[bj139]

Would that bcg work with a regular charging handle and upper?

No. I have the BCA side charger and this ambi charger.
Each have a plug at the back where the charging handle would stick out.
I suppose if you were a machinist it could be made to work.

Hmm... do I want to play machinist?

I just realized I misread this question.
I thought you meant the receiver.
The BCG should fit fine in a standard receiver as Randy said, with the handles unscrewed.
Still the question popped into my mind, can I fit a charging handle in this receiver with a Dremel?
I will take a look.
