If you still have the mod that removes the Brothers Grimms' iron sights (x_basset_o_standard), delete it since it's now part of this mod.

Removed some crap on akimbo weapons :

• Brothers Grimms, Kobus 90, Signature : iron sights
• Swedish K, Tatonkas, Micro Uzi, Jacket's Piece, MP40, Mark 10, Jackal, Patchett, Cobra : stock
• SpecOps : vertical grip
• Goliath : iron sights and vertical grip
• CR 805, Vertex : iron sights, stock, vertical grip

Also includes a version that only removes stocks.

I couldn't remove the CMP and Jacket's Piece vertical grip because they aren't actual attachments and I didn't do the Uzi because it looks nice.

Note : To get rid of attachments you need to buy the guns again. Same if you uninstall the mod to get the attachments back.
