First unfired impressions are that it looks maybe even better than Romanian standards on the AKT98/WASR22/RAK-22. It isn't super hard to install as long as you push down on the hammer. I was hoping the barrel insert would be past the gas port to possibly prevent fouling, but it is definitely shorter. However, it may be just short enough not to cause lead "misting" like that I see inside the blast chamber of a .22 suppressor. Clean up will be one of my questions along with ejected cases getting stuck under the dust cover (common WASR22 platform issue), but right now the bigger issue is with the magazines. The magazines are robust with a BHO follower. However, similar to my Chiappa RAK-22 with the Black Dog Machine WASR22 magazines, the magazine doesn't latch all the way in on my recent Romanian build with Nodak Spud NDS-3 receiver. When I get more time tonight I will update this post with some other AK fitting tests.
UPDATE: Mag latch is only an issue with one rifle, doesn't seem totbe a fault of the conversion kit. It fits my M92 built off a Morrissey underfolder receiver and Yugo mag latch, another rifle built off an Romanian parts kit, and a MAK-90. The instructions say that other than Yugo or Romanian AKs may need "minor gunsmithing," but it at least installed in the MAK-90 easily.
One other observation, the bolt handle is located much further back than even the WASR22. When uusingit for training and not just plinking I think I will still try to index where the normal bolt handle is and move back to catch it. Not the best solution but otherwise it is potentially a better training tool than the WASR22 if you have AKs that are setup multiple ways.
