Help ID carbine handguards

[ouchonyee]

Picked up this set a couple years ago only, but havent seen another like it.
Look and feel better than any other aftermarket copy I have seen.

Marked 8448738, OKT 3L549 on heatshields.
Colt handguards also pictured for comparison.

Quick search shows it was made by ok tool and die, and is a government contractor. but still dont know when they were in use..

If anyone knows which handguards are marked 'usa hgw 1', there is a set forsale with black heatshields I am looking at also.

I put in the question to some guys that may know the answer to your query. I hope to have an answer for you today.

No answers just yet. Still waiting.

Thank you for asking!

My preliminary search shows that CAGE 3L549 is still an active contract, meaning OK Tool and Die are still making them for M4s.

The handguard I have is the skinny round one..

update: Saw some page with nsn listings, and OK Tool and Die was making some knobs and covers, I am assuming not rifle related. Perhaps the current contract is for other parts.

Also I found some 3l549 marked A2 grips, new in the bag that were made in 1987 and 1988, so that is probably around the time my handguards were made..
