So I am building a 5.5" 9mm AR and have always wanted a side charging AR and a pistol caliber one seems like a good idea.

My delima is I do not like most of the current side charging uppers on the market, I do like the way the old LAR Grizzly side charging uppers were made/look.

I have a Mega MML upper assy and was wondering if it was possible to have it machined for a side charging like the LAR Grizzly uppers were? And if so who could do it ADCO?

LAR Grizzly side charging upper.

Here are a few places that do side charger modification you could check with.

Accurate And Reliable Rifle SIDE CHARGE HANDLE  MODIFICATION


D&L Sports™ AR-15 Side Charging Handle


Keystone Accuracy Side Charger


AR U199, GAS BLOCKER PLUG FOR SIDE CHARGE UPPERS ( REPLACES CHARGING HANDLE) ONLY $7.50

I machines a slot of the left side of one of my uppers and sent the BCG out to be drilled and tapped
i like it for the most part, but i dislike the reciprocating handle
