Mag58/M240 Rivets:
I had been contacted a few times in the past about Mag58/M240 rivets but didn’t think there was enough demand to put together a purpose-built set. Then I noticed an uptick in FN30 rivet sales, which is odd. Come to find out, some guys over at Weapons Guild were buying them to use the 5mm rivets in their Mag58 builds. For the 4mm rivets they have been buying commercial 5/32” rivets (which are within 0.001”) and turning down the heads to the correct 60 deg. angle. One of them finally contacted me to see what I have in 4mm rivets. After some research on my part, and a good bit of caliper work on his part, it looked like I could put together a set of rivets and offer them to a handful of BETA builders. Based on their feedback, I've assembled and am now offering a set for retail sale. My 5mm and 4mm flat head rivets have the correct 60 deg heads and appear to have the correct head diameter as well. The lengths are not correct, but they are easily shortened. Volume is too low to custom make all rivets to the actual spec. lengths.
As always, I want to put together the best set I can and offer it at a reasonable price.

Basic rivet set to assemble Mag58 or M240 LMG. All Flat head rivets have 60 deg. heads but are longer than specified in factory drawings. Cut to appropriate length before peening. Rivets are as described.
Updated Rivet Set:
Notes:
RH Roundhead
FH Flat head
1) Rivet is longer than required.
2) Existing head may be used with new Side plate, or head may be turned down and peened on both ends.
3) Spec. rivet is 3mm, which I do not have. 1/8" roundhead rivets provided which may be peened on the inside.
4) Spec. rivet is 3.5mm, which I do not have. 4mm rivets provided.
