CSA carbine NEIT/NEA parts fit

If you needed to split it off, it should have remained here.

if you felt it should remain here then you should have started a thread here but since you hijacked someone elses thread and i felt only wolverine could solve the warranty issue so therefore it belongs over there .

now back to the topic.
 
Plugging the holes left after removing the scope mount mount that obstructs the ambi safety.

This looks like the fit. Used my Mastercraft feeler gauge and came up M5-0.8. Depth of smallest hole is approx 4mm (rear hole protrudes directly into receiver)

Its nit-picky. But I don't like to leave them as is. Others might not either, so when I get a set home I'll snap a pic of how they worked or did not.
 
First shipment arrived:

NEA upper and lower Hand guards
Crusader brake
Ambi Mag release
Decals

First off, the decals went up on the gun safe. The crusader motif rocks, and the NEIT arms logo itself has some great celtic roots.

Before I get to the new shipment, I will also mention that I added the FO front and rear sights. Red front, green rear. Installation was fairly common sense. Rather than detailing here I will simply mention that Youtube has a shiztload of video tutorials on suck topics for the timid, mechanically retarded and unfamiliar alike.


With that said, to the new parts themselves.

First up, the hand guards. Tight fit. Had to use care AND force in order to seat them. Con is that they won't be going on and off. Pro is that they wont be going on and off OR melting off. They fit extremely tightly, and that works by me. They will not accept an Eotech 552, but a whole host of other sights will work well with it. to that end, I plan on using a T1 Micro for its light weight (consistent with the platform in general) and its ability to co-witness.

Much thanks to James and the TSE crew for helping me source one today. Worlds fastest service right there.


Next up, the crusader muzzle brake. Fit and finish is excellent and looks the part to match the new hand guards. I will be testing it against the factory brake (which was outstanding during the 1000+ round torture tests) this coming weekend. Like all other brakes I have tried, they do not close tight and lock. Screw on all the way and then back off a quarter turn or so to lock the detent in place.

ETA: After having looked at this more over the last few hours, I have found that the milled groove for the detent is slightly too narrow for the CSA. Going to examine against another Cz if I can get my hands on one. If necessary, I will correct with some light removal of material with a round file.



Last in this shipment was the Ambi mag release. To be honest, I am still f**king around with this part. It is likely something simple on my side of things, but I could not get this installed so as to properly seat a magazine.

The travel of the RHS of the mag release is impeded by the outset spline of the CZ58 magazine. On insertion of the mag, as it is rotated into position it can only be seated and 'locked' with considerable force. Removal looks something like a bear trying to open a tin can of food while balancing on a ball. I was about 15 seconds away from the dremel, but will wait to confer with other CZ owners MUCH more familiar with the platform BEFORE fuzcking with something that likely works when properly fit.

Resolved: Nothing a 3 lb hammer and a vice couldn't solve. IMHO, the bend angles on the factory piece need to be slightly increased. Maybe 10 deg more to accentuate the space between the RHS mag release paddle and the magazine spline. I am now down to a small issue of the paddle not being reliably forced back once mag is inserted, but this is a fine tuning element. Before anyone goes to whinging about 'proper design' bear in mind that there have been dimensional differences reported between the CSA carbines and the original 58/858 series guns. At no point have I had to break out the dremel here.

I have to also add, I am very satisfied about the finish on this part. It is TOUGH. For a part I put in a vice and beat with a hammer it looks better than some parts that have simply been used for a year.



Will complement with pictures as time becomes available. (largely stuck in the house because of GP snow fall).

On the way next are the ambi-safety, mag release and M1913 hand guard rails. The horizon? Well, it looks bright. I have been badgering Dave out of band for information on a release of an ambidextrous bolt carrier. As it is not my place to make any statements about product release, I can only raise the query again in this thread. Thanks Dave. You remember the old adage right? Your reward for great work is double time.

It is true, some such parts can be procured from the US in the interim. But these parts are superbly Canadian made, available from local vendors in country, and sans red tape at an international border. More, I think it is no stretch to say that NEIT and NEA have outpaced foreign manufacturers in fully modernizing the CZ platform. Outstanding work gents.


If current parts are any indication, this is going to easily seat as my current favorite rifle build.

Added on Ambi safety today.

Took about 15 minutes as I've never detail stripped the receiver into the trigger mech before.

4/10 on difficulty scale. Common sense applies.



I did not have issues Stevo reported prior to this thread being chopped.

I can only presume that the cause of this (sight unseen) is that our guns have slight differences. My pins are held in place by removable C clips, and were easily reinstalled. The milling on my factory selector bar is slightly different than that on my NEIT ambi safety. But again, dealing with the sheer number of variants on the Cz seems to present a bit of a moving target for designers.


Only ergonomic issue to me is that the edges on the LHS knob are SHARP. Rake a knuckle across it at high speed and you are going to lose skin. I will be taking a file to mine and dehorning.
 
You can say that again.

I'll get to photos this weekend. Too busy for pics at the moment. I think we need to get these guns introduced to each other and compare/trial parts across guns.

Weird that there APPEARS to be so much variance. Before any jumps up and down giggling nonsense about WTF, we should take a closer look.
 
Some shots of the Carbine assembled. Pictures are from my cell phone as all our camera gear is out of town for the last week.

Thanks to Wicked Police for trades on Larue FUG and to super rapid ship from the crew at TSE. Also my thanks to Wolverine for the quick Mag shipment.


Overall impressions:
So far I'm loving this build. Maybe even more than my last SAN CQB. Most notably, it is infinitely less expensive to shoot.

Yes, I am aware that the additions on the gun are worth more than the rifle itself by a large margin. But I like these particular pieces on any gun I shoot as they are functional, robust and light weight.

I debated the new Eotech XPS2 or 3 and discussed with BigRed at some length. But he talked me out of it and back onto the Aimpoint T1 Micro. We agreed that I was being torn away by shiny kit syndrome from an obvious working, co-witnessing solution.

Factory folder still installed. It is... adequate. You'd need thumbs like a friggin pervert to manipulate the stock on this particular rifle on anything but the shop workbench.

Thanks to an order from Stormwerkz, this is soon to be just a bad memory.

In this picture, you can see the extension of the release. Just a c-hair over the edge of the receiver. I have tested the dog s**t out of this and it is definitely FAST. The test carbine on the 1000+ round torture test was relieved on its side, making mag changes slow and cumbersome. Actually, that doesn't even cover it. With gloves on, it was downright unworkable; at times feeling like I was outright impaired.


With the extended paddles, I can pull a fresh mag and disengage the Mag release with my trigger finger (when firing right or left handed). Simply knock the empty mag forward and out and reseat the new. IMO, it is a whole new lease on functionality for the Cz.

My non-ambi bolt. Waiting for release of an ambi replacement. Some might not consider it necessary. To each their own. For me, this whole project is an exercise in testing revitalization of the Cz/Vz platform as a viable modern carbine and I find fully ambi controls a very desirable feature.

Also shown are the hi-vis replacement irons with FO elements. They pick up the light very well and are fast to acquire on targets under 100m

Here in this photo you can see the tapped holes in the receiver from the factory rail mount. s**t canned that ### POS early on. You should be able to see that the ambi safety will not install properly with that piece in place.

Have screws inbound from Fastenal to cover the holes.

Dave: Here is the new angle for the ambi mag release:
photoA.JPG

The picture is grainy. Will replace with another from better camera in production lighting. But you might still be able to make out the enhanced bends in this pic. As I said earlier. Fixable on a vice with a 3lb hammer.

Making it function properly with all of my mags seated and tested was another matter, requiring an hour or so with a flat file.


FWIW, it is a fantastic part. But the fit on current gen mag releases for this PARTICULAR rifle is off enough that people who want a tinkering free solution might want to wait for the next release, or get a handy friend to install and test it for them.

^^^ Nice build. The Ambi bolt carrier will rock your world. This combined with the ambi mag release makes reload drills a snap. Speed reloads were fairly fast, though I could not get my mags to drop free by smashing them with the fresh mag. I think I'm going to have to sand off some of the paint so that they drop free when I hit the release with my index finger.

I was out testing the set up yesterday with a good friend who had his bone stock 858. He basically could not do a decent tactical reload with the OEM set up. You can't reach the mag paddle with both mags in your hand unless you have huge gorilla hands. You need the extended release to make that possible.
