Would alternating drill and live rounds in disintegrating link gun offer the same solution?

Larry Vickers has a review of the Negev where he and the IWI rep discuss advantages of the semi setting. When I get on my laptop I'll post the link.

Best-kept secret??

Not really, many countries outside NATO have bought it. And Estonia iirc. But it came rather late to the market, much already taken by the FN Minimi.

i did get to hold it and fiddle it during basic training, but not to shoot. basicly it was not much liked i gather from local mil. board, maybe because we bought very early examples with kids diseases or not  just enough squaddie-proof . MAG/ksp-58 and MG-3 seem to be much more liked, esp. the first . however well made or not, it´s still 5,56 vs 7,62
 
edited to add. lots of our negev problems might have been caused by re-loading and re-re-re-re-loading ammo belts for training



The belt links are basically spring steel pieces, so yes they wear out over time. Rough handling does not help either. And early revisions may also play a role.


 

The whole thing of having semiauto to zero optics. It would be a bit of a faff, but why not just load one round at a time? A belt with one live and several dummy cartridges would do. Also, how do existing users get on with LMGs that don't have the semiauto feature?

With PKM, since it uses non-disintegrating belt you load one skip one.

 
The MG3 has disintegratng and non-disintegrating belts, but You should not skip pockets on the non-disintegrating DM1 belt, because the bolt is going to hammer against the belt itself and bend the link. I wonder If you could just drop in singel cartridges from the side? Hmmm
 
For the IWI Negev I'd just load a stack of magazines with one cartridge each. That should work I think. Though gets tedious if you have to zero several guns.

PKM uses pull-push, so no such problem.

Ah yes, right. And the extractor is not reaching as far forward. funny how the PKM's arrangement solves many small issues. And unintenionally so, because I doubt this was on the soviet army's mid, when the requirements were written.

Sounds very SAA like.

Or just use the semiauto setting on the selector switch :)

Good for Maxim and Browning, good enough for everyone else. Browning was categorical in rejection of the straight feed from a belt due the wasting all recoil force you have and instead investing in heavier spring so it would work well. While straight feed is simpler than pull-push and in theory has fewer failure points, in practice it also produces own problems for a designers to cope with.

Well the maxim gun had to accomodate the rimmed cartridges of the time. The advantage of using up some of the recoil energy is an at first unintentional effect from this requirement. Same for the PK machinegun. It was required touse the same belts already in use, which were of the pull out type. Funny how a complication can have useful side effects.

Straight feed is possible with rimmed ammo also - se Czech vz.59. Even PK's competitor, PN (Nikitin) used it.

Yes it is possible. The finnish also had designed a 7,62*53R conversion for the MG42. but it seems to make for more complicated and thus expensive belts.

It seems that Hi-Point didn't think that Boaty McBoatface, Brexit and Donald Trump were proof enough that asking people what they want is a bad idea.

Especially when you consider the votes of only a few hundred persons taking part. some individulas probably voting multiple times.  To put it out there seems like a good idea in a management meeting at first, but it attracts the jokesters. From the C9 model they just should have gone to D9. (and D45, D380, D40) maybe add a suffix like "Tactical" for the threaded barrel model. Or "S" for silencer. Or prepare it and make it ready to take a red dot and call it "the real roland special" :D
