How tough are screws to source?  I like the price, a bit curious what Id have to modify to fit a socom profile barrel.

Depends on how far the nearest Menards, Home Depot, or Lowes is.

Shouldn't have to modify anything that I'm aware of.  i think the RAS requires .835-.855" max barrel diameter at the front sight.  If memory serves (someone correct me if I'm off of course) the socom profile is the same diameter as the "beefy" parts of the gov profile where the RAS attaches at each end anyway.

$10 on Ebay or a trip to your local hardware supplier will get it done.

Zero mods for a true spec SOCOM barrel.

Pretty clone correct minus the lower. Just got the RIS installed.

Nothing. Fits standard USGI M4 Government and M4A1 SOCOM barrels. I’ve done hundreds of them

The partially removed paint adds to the clone correct-ness of the lower.

Pardon my ignorant questions.

Were any of the block ones set up with the OG redi-mags or was that never in use?

I got a couple of them a while ago (gen 1 style as far as I can tell).

Seems like I remember the military using them in some areas a while back and seemed like it would fit in with an early GWOT style M4 build.

See page #113 here for some discussion on these.


But yeah, definitely found on B1 guns in the wild.

Yes they were part of the original early Block 1 items. I put one on my M4A1 in the late 90s but took it off due to balance being off. When you carry that gun more during mountaineering, patrolling, skiing, swimming etc it didn’t fit. Now if just doing CQB, FOB/house gun or convoy duty it’s more suitable
