Need help identifying this handguard

I’m trying to figure out the make/model of the hand guard on the rifle second from bottom, and the rifle at the top?

Bad link to photobucket

Now it’s workin

Which rail are you referring to? I saw three in the picture. None of the pics are very detailed either.

The rifle at the top, and third one down

Im not sure but from the barrel nut, it looks like one of YHMs offerings.

Bottom looks like some YHM offering, middle looks to be a Spike’s BAR rail, and I’m not sure of the top one.

Is the top Samson? Or YHM?

Top one. unsure. The bottom one you are requesting. I think its a YHM. but discontinued. i haven’t seen that rail in awhile.

3rd one down looks like a spikes tactical or seekins precision BAR rail.

I think the rail on the upper at the top of the picture is made by a company called “Young Manufacturing”

(pic is from CheaperThanDirt.com)

The attachment on the 3rd rail down looks like a dead ringer for the Seekins BAR as it lacks Spikes logo on the barrel nut end of the rail.

Thanks guys for the help!

As stated it looks like the 2nd from the bottom is a Spikes/Seekins BAR. It from counting the slots for venting it looks like the 10in version.
Hope that helps.
