The initial trial batch produced for Army trials had failed the MRBF (Mean Rounds Between Failure) parameters. OFB had hoped that quality in production could be stabilized if they get some orders from CAPFs and Police units first. They did get several orders from MHA forces. However, I haven't heard anything regarding them submitting a fresh batch for re-trials. In the meantime IA couldn't wait till eternity for Ordnance Factories to figure out how to get consistent quality control across a production batch, and decided to go in for the foreign carbine tender. Now, obviously there aren't any rifles/carbines in production right now in the world that use the 5.56x30mm cartridge (Colt experimented with some models in ages past, since abandoned). So 5.56x45mm was only choice. Personally, I'm happy we went in for the x45 instead of the x30 MINSAS. The x30 in my opinion is a half-a$$ed cartridge. Neither it offers the small dimensions & light weight afforded by pistol-calibre rounds like 9x19, nor the full power of a rifle-calibre cartridge of 45mm length. The whole point of having a small gun is that it should afford a good compromise between size & stopping power. In an age where one can easily get carbines firing full-power rifle rounds with 11" barrels and weights in neighbourhood of 3 kgs, the utility or reasoning behind creation of a weapon in similar dimensions & weight but shooting a much less powerful midrange round like 5.56x30 frankly escapes me. However, if OFB manages to reduce the weight of the JVPC to around 2 kgs, and trim its bulk, it could be an interesting alternative to the HK MP7 that many SF units might want to get their hands on (if quality control could be fixed, that is). But I have doubts how well the recoil of a 5.56 bore (even with the less powerful x30 cartridge) can be controlled on a 2 kg weapon. They may have to tune down the calibre to something similar to the MP7's pretty effective 4.6mm in order to be an effective & controllable PDW.
