Good option for State Compliant Rifles
I have this item installed on a Windham Weaponry SRC (NJ Compliant Model). As my rifle is an NJ compliant model, it does not have a bayonet lug and Harris # 5 seemed like a good option to mount a bipod. My rifle has standard handguards with the double heatshield. On a carbine model, this adds a little extra work to the install because of the location of tabs within the handguard.. Once the handguards are removed, the inner heat shield must be pulled out from the tabs inside with a pair of needle nose pliers. The outer heat shield should not be removed. There are tabs inside of the heat shield that is in the way of the harris adaptor. There are 6 in total, but only the ones at the end are of concern. The ones near the end are in the way of the adaptor. They should not be in the way on a rifle length handguard. The tabs need to be cut with wire cutters. This leaves two small buttons that must be filed or removed with a Dremel tool, or the inner heat shield can't be reinstalled. Once the pins are removed, the adaptor will fit flush and appears to be of the same thickness as those buttons. The adaptor should be installed in the second hole on a carbine and third if you have a rifle. The outer plate should be installed, and the stud tightened. A drop of blue Loctite on the stuf threads would seem wise. At this point, the inner heat shield may be reinstalled, and the four remaining tabs seem to hold it correctly. I have not yet shot the rifle since installing this adaptor. The adaptor is not intrusive in any way and only adds a sling swivel to the handguard. With the bipod installed, it seems very solid. Only firing enough rounds and time will tell, but this does seem to be a good solution for state-compliant rifles without a bayonet lug or bottom rail to use a bipod.
Colt AR bipod adapter
Didn't work on my Colt Mdl 6920. Heat shields are integral to the handguards; can't remove them to mount the bipod adapter.
Harris Adapter Stud Swivel #5 AR-15
Did not fit S&W AR-15 with a little modification. Had to modify bracket by cutting ends off to fit without damaging pins that hold the heat shield. They say not to remove the heat sheild, but I found it fit more solid by placing under the heat sheild and slightly bending the heat shild to fit back into it's original place. I also used a little blue lock tight as normal with parts un any gun. Holds my bipod good and solid, and have had no problems yet.
