Hand guard could be either: a shallow groove 2 or 4 rivet.
At 5,8 yours is in the latter part of a transitional period, where newer updated parts are/were becoming available.

I have WRA 5,811,227 with adj rear site, flat top bolt, 2 rivet shallow groove hand guard, type II barrel band (no lug for bayo).
My stock has a long barrel channel measuring just over 4", you normally see the barrel channel just over 3" in this range.

Hand guards:
There were 2 that came with 2 rivets.
Type I is early with a deep sighting groove.
Type II is next with a shallow sight groove. Thicker cause they cracked as Type I's.
Type III same as Type II, but with 4 rivets.
