Wouldn't be surprised if some day IA RR and SF borrow gear, equipment from J&K SOG and CRPF QRT.
RR is actually doing relatively well. They see a lot of action on the daily and in recent years have also been keeping up with evolving requirements. When they inducted the new ACH helmets and found that they could do with an armour upgrade, they immediately started ad-hoc orders for applique armour kits, while they also put out RFI to procure larger quantity of them down the line.
Don't forget RR were also the first to introduce FAB Defense kits for upgrading AKs in a big way, to make them able to mount optics. And RR probably has the highest optics-to-guns ratio in entire Army (barring SF).
The rapid modernization of CAPFs can be credited to Mota Bhai. Amit Shah has streamlined the CAPF budget smoothly, and there are working on a yearly procurement plans which are expedited on a timely basis.
Rajnath Singh on the other hand is doing Kadi Ninda, and most of the army RFIs issued since 2016-17 are stuck, with only a few emergency prcurement from abroad.

The streamlining of MHA procurement certainly happened during NDA govt but it preceded Amit Shah's tenure. Either which way, one must remember its never the Minister which sees these things through - it always has to be the bureaucrats. If stuff is going bad/staying bad in MoD its due to bureaucracy and if stuff is going (relatively) well in MHA its again due to bureaucrats. Of course the Minister can choose to employ better/worse bureaucrats depending on their domain expertise or work ethic, but for the most part the job of Minister is confined to making Policy decisions and signing on whatever dotted lines the Secretary of Defence & his minions furnish up.
As of MoD, I've no hope for the bureaucracy in that Ministry, whether its Rajnath Singh at the helm or anyone else. If Manohar Parrikar couldn't make everything right, then no one can. Only hope is the Dept of Military Affairs taking shape and taking much of the procurement process for small(er) deals like infantry equipment away from civilian bureaucrats.
