Scope of project: I have honestly wanted a bullpup for awhile. I went down the path of the Shernik for the SKS but after 8 months, I was tired of waiting. Acquired a nice 410 with 3 10 round mags for 3 bills and then found the Kishnapup and decided to go for it. I wanted a PDW that was as short as possible and could be used by both myself and my wife for home defense without the tax stamp hassles. I also may challenge the east Texas hog population to some CQB. Finally, I want to eventually build a short rifle in 556 or 545 for my BOB but the jury is still out on whether this will fit that need.
Overall Impressions: The stock seems flimsy as you pull it out of the box but once installed, the stock seems very solid. IMHO at least as good as the standard Saiga furniture or an AR. It is a very nice looking bullpup IMHO. OK bullpus are ugly, but this one isnt that ugly! INstallation is pretty straightforward with some plastic trimming her and there, but the instructions suck. Mainteneance should be pretty easy as you only have to remove 3 screws to get to the top cover and a little screwdriver is stored in the pistol grip. Cleaning the gas tube on a rifle conversion will be a little more challenging. IMHO the trigger pull is a vast improvement over the stock trigger pull and is as good as my converetd Saigas.It is not as light as my converted Saigas but has a definite 2 stage feel and a pretty clean break. The trigger mechanism is simple with only 3 moving parts but the trgigger itself is plastic and rides in a plastic channel. I have to wonder how long it can last, particularly under the recoil of a 12 or 7.62X51. The stock gets it's strength from a ribbed design rather than a lot of solid plastic. Again, it seems very solid once installed but may require some JB weld or acraglass filler here and there to beef up the recoil areas. This stock dramatically improves handling. The gun feels much lighter than it's 8.25 lbs and I beleive it could be shot easilly with one hand. Mag changes seem no worse than the usual AK rock and lock. They are made with the weak side hand and some training will be required. It seems very easy to keep the gun up and on target during a mag change but live fire tends to change impressions on that. I cant completely endorse this stock yet, as I have no live fire experience, but it seems very suitable for the 410, 20, 556, 545 and 7.62X39 Saigas. Particularly in a home defense or casual shooter role where the reality is that 1000s of rounds wont be fired through the weapon. I'm not sure it would stand up in the long run to the 7.62X51 or 12 guage, particularly under heavy usage, 3 gun competition and the like.
Easy straight forward install
Drops 13.5 inches from the OAL of any Saiga
Good trigger pull
Plastic trigger riding in plastic rails.: I would love to see an aluminum trigger option for this stock.
The tang is supposed to be cut off : I couldnt bring myself to do this, so I cut a slot in the buttpad and the tang stick out 1/2 inch. It seems to ride above my shoulder but the reality during live fire may be different. Kishnapup website says they are working on a buttplate that will cover the tang and I will probably fabricate my own.
Not optics ready. : A gas tube rail or other sighting system will be required. I am waiting on a 410 rail from CSS that is supposed to be ready in a couple of weeks.
Expense: The stock is a little pricey at nearly 3 bills shipped, especially since you will need a $100 rail for your optics.
The instructions suck.
Here are a coupl of pics. The rail is just a mock up using a piece left over from my 12 conversion.
I hope this helps some of you who may be interested in a bullpup Saiga.
