I'm still working on this....slow progress due to a sick family and other stuff on my plate.
Working in pairs is a good thing.
As you can see, I'm doing up a pair of trunnions as well, and am working up a mock "Gas tube" to provide some real strength between the fore-end and the receiver trunnion.
Adds a bit of weight, but BOTH of the minimis had their fore-ends bent (one a bit, the other a LOT) due to use. With no battery pack in the way under the barrel, there's no reason not to re-inforce this area.
