Gunsmithing Hook spanner insert

[FS1]

Does anyone know of a manufacturer that makes a hook spanner insert for a stahlwille torque wrench?

If not what do you all use for setting torque on a buffer tube nut. Specifically for an H&K but any info on any other would be appreciated.

I use a DPMS castle nut wrench, it has a broached hole for a torque wrench. Calculate offset and go to town.
That being said the torque value on a buffer tube/castle nut is not overly critical. 25-35ft lbs is plenty. Maybe a drop of blue on a buffer tube and stake the castle nut.

Thanks for the info I will take a look at it. I am not sure if it will work with the MR762.

I can find hook spanners that will work but not with the cut out for the torque wrench. I need 60 newton meters or 44.25 foot pounds of torque. I like to do it by the book. Torque sometimes can seem arbitrary but if they call for 60 NM that's what I want to give them.

If Anyone has a MR762 and wants to change the buffer tube to the g-28 style? This is how I did it. Constructive criticism welcome.

Klein torque wrench

adjustable hook spanner from samStagSales.

30mmx40mm round stock cut from a 1 3/16 (30mm) shaft stock.

Staking punch ground down on a bench grinder from and old broken 1/8 in punch. I think its about 3x1.5mm.

Need to calculate the extension from the square drive center to center with the spanner. The set torque will be lower than the applied torque.
