Hey all,

I've been searching the internet for hours trying to find accurate dimensions for the 55x lower receiver to no avail, so hoping someone here can help me. I'm specifically modelling the 552 commando, but believe the lower receiver is the same for the 550, 551 etc

Can anyone provide the width of the lower receiver please? (minus the push pins, selector switch etc, just flat to flat)

The length and height would be a bonus

Many thanks, Howie

If you’re in Ohio, I can loan you a lower to exam.

Unfortunately on the other side of the world, UK, appreciate the offer though.
