I ordered this for an 18" 6ARC build. The barrel I'm using has a Rifle + 1" gas system length. This handguard just covers the low-profile gas block used on that build.All the quality, fit, and finish you've come to expect from PRI's round handguards, but with a flat bottom for use on bags. The high peak also looks like it would clear most piston systems, as well.

I chose this over the round version since it is similar to the M-16A1 forearm which was very easy to hold. I sold my vintage Colt A1 upper and regret it. The advantage over that is it does not have a taper design and is good for using the forward most hand position many shooters practice today. It is stiff and feels solid. The inside is not painted and you can see the real carbon fiber structure. There is clearance for most adjustable gas blocks. The triangle shape fits my hand perfectly and I like this better than the KAC M-16A2 RIS. Very expensive part, but you get what you pay for. Would have been Five stars but gave it four stars since the top rail is slightly higher than the flat-top upper receiver rail and an additional connecting top rail is needed for using BUIS. Great product from PRI and OP.
