Default Any advice on a 458 SOCOM upper?

Trying to build an accurate 458 SOCOM. This will eventually be suppressed shooting subsonic loads for hunting Pigs at night, and supersonic loads for deer.

I got an inexpensive (not cheap) Aero Precision lower, now I'm looking for a good quality upper. Reviews on all the inexpensive ones have made me think I need to spend about twice as much as planned to get a good one.

Right now the two most viable options are Rock River and Tromix. Building my own with high quality parts seems to be more expensive than buying a Rock River upper. From reviews it seems Aero used to make a great 458 SOCOM upper that wasn't too expensive, but they no longer make them.

Already got the 410 grain SubX bullets. Dies and brass came in today. Mags should be here in the next couple of days, and the lower should be arriving at the gunshop by the end of the week.

GLFA was one of the better, but they seem to have quit playing.

Here are a couple of review sights.

If this is your 1st. foray into long stroke AR's I would recommend doing a complete upper. That way you're not in piece part fitment hell.

I have a question for you AR gurus.
I have a milspec buttstock with the fixed sling swivel and a webbing slot.
How can I put a QD mount on there? Is there one that can replace the fixed sling swivel or that attaches to the webbing slot?

Good question. I don't use QD mounts on the buttstock only on the foregrip.
Here's what I found. Hope this helps.

I've used Midwest Industries products in the past. They're good quality.

Thanks!

I think for now I'm going to just use the QD for the front, using an M-LOK QD swivel, and clip onto the stock sling swivel on the buttstock, and worry about the rear QD swivel later.

I ordered this sling from Amazon:
