Wonder if they’ll attempt to make a JVPC with a Milled Receiver.
probably not, it already went through all trials, there does not seem to be any need for such design revision, but if done then it would work yeah - probably increasing its mass-weight about 300-400 grams more though
although it DID have AK-styled construction prior to current two-section receiver build i.e. this,
apparently this cover of some russian/ukrainian defense magazine is one of the few high definition photos of original MSMC out there
anyways here, note the typical AK-styled top cover and single piece receiver build, clearly from INSAS i believe; had bumped section on trigger side, INSAS styled flat profile bolt carrier, INSAS style sights and that top cover locking button or pin or some arrangement at end
aanndd IT ALSO HAD GAS CUT OFF LEVER ON ITS GAS BLOCK, STRAIGHT FROM INSAS!
DID THEY HAVE IDEA OF LAUNCHING RIFLE GRENADES FROM THEN MSMC OR WHAT ?!
also, bottom bayonet mount was from INSAS but for what purpose was that top mount thing ?!
coming back to receiver, it seems the visible polymer part was a just a big single-piece enclosure plus structure made of injection moulding or whatever, for giving it required shape of a uzi-styled weapon, also housed that retractable buttstock
later they seemed to have revised this design - instead of big tavor-styled open guard on pistol grip (for operating it in cold environment with those mittens) they replaced entire polymer enclosure+structure with newer one, now having a smaller trigger guard only covering trigger finger (probably it detached and hinged down along with pistol grip like in AR-15 or so for operating it in cold environments etc), finally they also revised pistol grip (new shape plus dotted pattern on it for probably better gripping) and extending from handguards, a set of polymer protective ears around...metallic protective ears of the front iron sight post ?
probably to cover gas port to prevent shooter's fingers-thumbs etc touching there and getting burned...
(sidenote, remember i mentioned
sirji himself mentioned it that he had trialed MSMC//JVPC and complained about how butt was hitting on the face of shooter plus one could literally pull it out of the weapon etc ? this pics are from same post on Shatrujeet Facebook post on it)
at the end we got our well known version of MSMC later named JVPC which got a complete revision - now has two-sections receiver design plus revised polymer enclosure+structure AANND GAS CUT-OFF HAS BEEN REMOVED as well as top mount just above bayonet mount is also gone, among other differences (i have mentioned more than enough, you guys now point out differences on yourselves *phew*)
so there you have it, MSMC and JVPC designs thorough the history
