Hello all,

I'm almost embarrassed to ask this but after an hour of scratching my head I know when to ask for help.

I bought the backplate sling adapter from the H&K web store. (Part number 227675.) Has anyone else bought and installed one of these? Do I need a special tool to remove ring that holds the existing plate in place?

I've read the manual from front to back with no luck and the H&K website doesn't have any instructions. Is this something covered in an armorers manual?

Many thanks in advance,

Jim

Don't be embarrassed; questions are just as valuable as answers because they cause others to pause and think...

Yes, there is a special tool used to remove the nut on the buffer tube. It is commonly called an (M4) armorer's wrench. The wrench has teeth which fit into the recesses located on the nut, enabling you to apply the torque necessary to remove the nut. They are an inexpensive item (~$15-$20 on average). Just remember that buffer tubes (and the wrenches used to remove nuts) come in two sizes: commercial and mil-spec. Be sure to get a wrench that will fit the mil-spec tube.

Nocomp,

I thought that might be the case. Thanks for the swift reply.

Are there any wrenches that anyone has used that they would recommend? A quick search this morning yielded a very wide field to choose from and I would rather have something that works from someone's experience. (There seem to be conflicting reviews on the Tapco on it's being mil-spec.)

Thanks,

Jim

I would think that any wrench from a reputable company would suffice. The one I used came in an M4 armorer's tool kit purchased from Shop Shooting Supplies | Reloading | Gunsmithing | Hunting gear — MidwayUSA.

Some wrenches can perform additional functions due to their design, and the cost will likely reflect versatility of the wrench. I don't have experience with other wrenches, so I can't say that one is better than another.

No wrench in particular, but just be advised that the "you get what you pay for" applies. I've broken a cheapie AR wrench before.
