I'd considered the same rig job, but wanted to use something more purpose built if possible. My upper is an Aero M5E1, so I'm wondering if it would fit those clamps?

I have a 5.56 Geissele RR, I may try it. Won't have my receiver set until tomorrow to see.

I'll check out Brownell's.

Thanks.

Purpose built? Working on an upper is the purpose of of receiver blocks.

If you have a top rail (yes) and two lugs for the pivot/takedown pins (yes) then the blocks will work fine.

A 5.56 reaction rod won't work in a large frame AR.

The blocks I linked are the cheapest way to do what you want to do.

[Last Edit: beatsAstick] [#7]

I was referring to rigging the upper by the barrel between wood blocks. I wanted to avoid that. I didn't expect the 556 rod to work, but if it worked on his 6.5, why not try.

I'll get those blocks, thanks. I should have looked/read how those work. I was assuming they encased the upper like a typical AR15 block set.

Great looking build btw.

the multi-blocks are nice. I wished I'd ordered them, but I already have a set of Spikes blocks (which apparently were discontinued). Got the 308-specific ones instead...they don't have the pin system.

More tools is always more better.
