I have a Stag model 7 left hand ar in 6.8mm SPC and want to change the forend on it to the Sampson evolution forend. what tools and parts will I need to accomplish this?
Already Tried: nothing, I dont want to damage the gun
Hi,
You will need a hammer and a punch to fit the taper pins, pliers and needle nose pliers. If you have a low profile gas block, it is very simple to do. If you do not have a low profile gas block or free float hand guards now, you will need a wrench to remove the flash hider if there is one. Most are 5/8". Use a punch to remove the 2 taper pins holding the gas block on. Look for the smallest side of the pins and drive them out from that side. Once the 2 pins are removed, slide the gas block with the attached gas tube off of the barrel. Remove the handguard to the front. remove the delta ring, spring and clip from the front of the receiver. Install the Sampson handguard and tighten the allen screws to hold it in place. Slide the gas tube and block back on the barrel and line up the grooves for the taper pins and install the pins. There are links to video's on the Sampson and Stag sites showing the removal and installation of the handguard.

Tom308,
Sorry, maybe I wasn't as specific as I should have been. Being that it is a Stag model 7 this rifle came with a hoague forend that screws onto the barrel? meaning there is no barrel nut for the Sampson evolution to "clamp" to. My rifle has a match grade 20" barrel chambered in 6.8SPC that came assembled from Stag arms, what parts will I need to be able to put the Sampson forend on.Will a regular barrel nut for a 5.56 AR work on my rifle if not what do I need to be able to swap forends?Stag offers an AR called the 3G but it is chambered in 5.56 this rifle has everythig that I want for my rifle just not in the right caliber. I have already changed the buffer tube on mine and put a different stock on. Before I take off the forend I want to make sure I have the necessary parts to put the new forend on I have looked on multiple web sites for info and have not been able to find any info on my particular rifle and what I want to do any info will be helpful
Thank you
All you need to do is remove the existing guard. There has to be a barrel nut on the gun. If there wasn't, the barrel would not stay on the receiver. If the barrel nut that is on the gun, (that is what the Hogue forend screws onto) is too small for the new handguard, replace it with a standard one. You will need a barrel wrench to replace the nut if needed, but I do not think you will need it. You can get a barrel nut for $10 and the wrench for $15 to $75 for an armorers wrench.
