Crazy Ivan Ruger 10/22 chassis

Since I didn't find too much info on the Crazy Ivan Ruger 10/22 chassis I decided to buy one and try it out for my self and share my experience with you all.

I was looking for someting that mimics the ergonomic of an AR-15 that could be used as a trainer for IPSC Minirifle competitions (which of course translates over to IPSC Rifle competitions where AR-15 is the main model used).

I really wanted something with as few take down screws as possible for disassembly and cleaning. Since there will be some volume of shooting done.
The NC chassis looks and feels good but seems to be a little of a hassle to disassemble.

First of the manufacturer was helpful and easy to deal with.
The overall quality is good although there are some sharp edges along the picatinny rail that I think should have been smoothed out before anodizing.

Instead of using the "thrust screw" putting forward force from the rear of the receiver. I decided to add a small screw in the same place as the Victor Titan stock does. This one snugs up the entire package by putting a small amount of downwards pressure on the trigger group. More or less working as a rear anchor.

The barrel nut and top rail is a solid one piece construction, i put some blue loctite under the entire lenght of the rail before screwing it down on top of the receiver.

I wish the buffer tube extension had been more in line with the barrel and not as low as it is now. One reason is that this would eliminate the need for a cheek riser and giving more options for grips and how high up you can get on them. I also think that there would not be space for a rifle A2 style of receiver extension (coming furhter down in the way of the grip). Guess this has to do with production costs (material and machining steps).

Overall I am happy with my purchase and it is a solid kit that I would recommend as long as the buyer is aware of the limitations.

To sum it up:
+Reasonably priced
+Good quality
+Solid construction
+Necessary hardware included, thrust screw, top receiver (scope mount) screws, grip screw (w/ washer), take-down screw (w/ washer and nylon retainer), buffer tube alignment ring, barrel-nut spacer, grip spacer
+Only one takedown screw!!
-Receiver extension height in relation to barrel and scope rail height (need for cheek riser and it also sets limitations to grip and stock options)
-Some sharp edges on the picatinny rail

Does anybody of you know of some iron sights that mount on to the picatinny rail that I could use on this build if going down the iron sight road? They cannot be traditional AR height that's too high for me since I would like to eliminate the need for a cheek riser. Half the height of typical AR sights is close to the correct height. Roughly 0.5" high sighting line.

Crazy Ivan Review

Thanks for the detailed and fair assessment Ludde, and the suggestions!

I struggled with the rear geometry when I was designing the chassis - I basically had two choices - make it mimic the AR geometry at the rear - but that adds weight and cost because it would require a larger billet and more machining (plus might have required a larger - and more expensive - upper to handle the transition) - or have it in line with the body of the chassis with the accompanying grip and stock issues. I chose light and less expensive - life is full of compromises - oh well!

I've already mentioned the rough edges on the chassis to the machine shop - this was only a problem with the first batch of clear ones we did (you have one) because they don't get blasted first like the black ones do. From now on, we plan to hand finish a little before anodizing to get the rough edges off.

But I'm curious (question to everyone out there!) - do you think the clear would look good blasted first so it is flat rather than shiny?

I'm going to evaluate your trigger group screw idea and it might be on the next batch I make - maybe have both screws so people can really tweak it! Thanks!

Tactical Style Soft Cheek Pads - 3/8 inch thick and Super Soft Cheek Pads - 3/16 inch thick - Magpul® PRS™---These versions can go piggyback (and so do the other ones but I am just judging the arch of your AR stock's cheek section) if you want it higher.

I have the dimensions (width and length) in case you want them. Btw, they taper off (the sides) to 1/16 or so, so they do not look goofy.

Another Crazy Ivan

Here is my version of a Crazy Ivan build.... This one was done to be completive in the Steel Challenge world of shooting

I too chose the CI chassis for its ability to add the hand guard of my choice

It is harder to break down than the PMAC because of the rail being attached to the receiver and part of my problem has nothing to do with the CI chassis but in the use of the SBX barrel with the welded sleeve to keep the gun from being a SBR

My over all satisfaction is a 4.75 stars

This will not work with receivers with a built in rail such as TI and TacSol

My cheek riser is a piece of pipe foam insolation attached with contact glue. light and just the right height for me



BTW I use 10 round mags for SC.... the TI 25 rounders are used for a Action Steel match each month

sorry did not realize that the above photo did not have the cheek rest.... here is another
