WS-MCR - Ongoing Impressions

Gatehouse said:
New development. Kinda weird.

My first MCR is still running fine and well past 1000 rounds. Other than the roll pin replacement and tightening the castle nut it's needed no attention.

My new MCR has only a couple hundred rounds though it and today it doubled, which was weird. I didn't see anything obvious so decided to try to see if it would repeat but it didn't and I was at the end of the magazine. Replaced the mag and then it went 2 shots then dead trigger. I looked in the charging handle slot and the hammer was in the fired position. Opened bolt and extracted a live round. Closed bolt and again, 2 shots then dead trigger and hammer in fired position.

I separated upper and lower and removed sear and hammer, surmising that one was defective and as I had replacement AR parts on hand thought I would replace both. Well, the sear looks similar but was slightly different than the AR sear I had on hand. I have had plenty of AR's and replaced plenty of parts and know AR parts from various manufacturers can have slight differences but I wasn't sure the MCR sear actually is a AR sear so I didn't want to experiment. The sear looked fine, anyway.

The hammer looked like it had some wear marks and a bit of a ding on it too. It was close enough to the AR hammer I had on hand so I replaced it. First time disassembling the MCR lower so I had to fiddle with it a bit but once fully assembled I tried it out and I fired a dozen rounds no problem.

Any ways it was weird. Still not exactly sure what was going on as I would think that from where the hammer ended up it should have doubled rather than been left with a dead trigger but I suspect it's due to the firing pin spring tension acting as a buffer from a hammer that went forward without full spring power.

Also, the hammer from my new MCR is different from the old MCR. I assume it's because they are using whatever parts they can source. Pics attached. Old MCR lower with failed hammer beside it

This is super disappointing to be honest. Thanks for the update and sorry to hear you've had to deal with this. I just recently replaced my factory MCR trigger with an ACT and not sure if relevant but I feel like it's worth noting that it was a direct replacement and the gun feels a million times better for 100 bucks.
 
Just received mine yesterday and tore it apart to check everything out. First off, for the price point I'm very happy with the gun and feel it is an upgrade over the WK I played with. Now for the bad, the machining is far from perfect. There are light tooling marks on the receiver and the outside of the barrel is very rough, not really a big deal in my opinion but yours may be otherwise. And as everyone is already probaly aware of the stock furniture is very cheap. The trigger is heavy but I think it has great potential for a dyi trigger job. All mags I tried dropped free empty and as a bonus it shipped qith a duramag which is more than I expected.

Just received mine today as well. Got the one with the Galil Folding Stock. Agreed overall for the price point its decent. As noted above there's definitely visible machining Marks on the receiver. Not the prettiest rifle but I'll take what we can get now.

Question for anyone that recently received theres. Did yours come in a hard case or a soft case? Mine showed up in a pink and black Allen soft case, in a cardboard box. The case doesn't fit the rifle whatsoever and just seemed a little random lol. No biggie just noticed in the past they came in hard plastic cases.

The newest WS-MCR has an option for a galil style folding stock developed with Specter, it feels very study. Upon disassembly I also noticed the firing pin retaining pin was changed from a hollow roll pin style to the AR-15 "cotter pin" style.

Odds are any MCR built since the first Galil stock full version was released has cotter pin instead of the roll pin style.

i havent seen any pictures with aftermarket handguards. Has anyone done this and any issues clearing the gas block with a Midwest/SLR/Fortis etc style handguard?
 
What height optics are guys running on the folding stock version? Is sight height still the same as an AR? Trying to figure out what height red dot mount to get. Also, how are you running a sling on the folder?
 
So what's the verdict on the most recent production MS-MCR as far as reliability and quality are concerned? Considering picking up a 7.62 model but am looking for a functioning, reliable firearm...not a project.

Ive "heard" that problems have occurred when part(s) at one end of the tolerance spectrum are mixed with those at the other. The cumulative difference between parts (which are otherwise in spec) causing an issue.

If parts are "in spec", tolerance stack shouldn't matter. That being said, I've had random problems with some AR lower parts that were solved by just swapping with the same part. Could just be tolerance stack issue as you've suggested.

I finally got my hands on a WS MCR at a gun shop and after the first impression wore off, I wasn't very impressed. Lots of sharp edges. Unnecessary ones at that, especially around the grip.

Same I got rid of mine before I even shot it. I'm waiting for the irunguns rifle, the ergoes look better and it should be a more polished product given the manufacturer.

I couldn't get over the grip, the squared off edges were plain uncomfortable. Sold mine, went T97, sold that and got an X95.
 
I just ordered one and for anyone that already owns one do you think a BCM handguard would fit over the gas black? BCM handguards are among the slimmest and are a tight fit on conventional barrels and gas blocks. Thanks!
 
My castle nut came right off, and that should be staked at the manufacture. Ah well, I just hand tightened the bastard till I got home. Still running strong. Mine has a few hundred rounds and it's still a great rifle. Anyone in the 3000 to 4000 rounds yet?

Some have mentioned sharp edges around the grip. I took a Dremel to mine and some black metal finish to her. Cleaned up great.

I put a little over 200 rounds through mine this weekend. It's one of the newer manufactured ones with left side charging only, 15" handguard and the folding stock.

Observations before ever firing it:

-This girl needs to go on a diet. Weight with no mag is 8.4lbs. I've seen everywhere from 7.4 to 7.7lbs as the weight of the buffer tube version but obviously that depends on whether or not it's ambi. I'd be curious to hear fro anyone who's put a folding adapter for a buffer tube on it as to what it weighs. I really don't know why they went with that particular barrel contour but I'll come back to that. For the sake of comparison, a Colt 6920 with a quadrail and an Elcan OS3X weighs 7.7lbs.

-Like others have noted, there are "sharp" edges. Not enough to draw blood in my case but I could see it chewing up your gear if/when carried slung. I get that it was built to a price point but if I hang onto it, I'll most likely be honing all the sharp edges and then having it cerakoted.

-The trigger feels like your typical, basic "mil-spec" AR trigger.

Observations after firing it:

-It will not run with any of my Pmags. They aren't over-inserted, I'm not smacking them in. Inserted with the bolt locked back, the bolt always fails to go into battery when the charging handle is released. The problem doesn't occur with the 2 provided metal mags (powder coated black and of unknown provenance).

-Yesterday it ran factory AE 55gr ammo flawlessly (in the factory mags) as well as some of my 62gr handloads that were what my AR liked. It had a few failures to go into battery with some of the 75gr handloads I tried in it as well but after measuring brass, it coulda been sized down a bit more (although sized like that it ran fine in my AR). It honestly felt like it needed to "break in".

-Today I worked up a load with some 55gr V-max (I got thousands in a trade) and further tested some 75gr loads. Still wouldn't go into battery using Pmags but ran all my reloads flawlessly in the factory mags.

-Accuracy was what you would get from a quality AR (not precision AR). Bulk AE 55s, my 62gr loads and the load I worked up with the V-Max all shot <2moa over multiple 5 round groups. The best load with the 75gr BTHPs was <1.5 moa over 2x 5rd groups. This was all with BLC-2 which in my experience doesn't really lend itself to accuracy. If I decide to shoot 75s, I'll revisit load dev with some 8208. All groups were shot prone with a bipod and rear bag and on 21x mag with a trusted scope (Bushy HDMR2). To be honest, I'm pretty confident that you could eke more accuracy out of this rifle with a better trigger (the stock trigger is no better or worse than what you get in a decent AR) and with a typical buffer tube stock as the folder doesn't make for a great, repeatable cheek weld.

-The barrel... the contour they used really puts this rifle into a funny spot, imo. It's got accuracy I'd be happy with in a lightweight carbine but it's no lightweight. I'd be ok with the weight if it was a match grade barrel and shot closer to moa but as it is, it either makes for a kinda heavy rifle with a red dot or a not quite accurate enough rifle with a magnified optic.

-Adding the bolt hold-open lever that RWA makes seems quasi-necessary. After clearing malfunctions without one, it becomes evident that it would be much nicer to be able to lock the bolt to the rear without having to stick your fingers up the mag well.

-The folder is stiff at first but seems to be breaking in a bit although lock-up remains nice and tight.

Where does this leave me? I got the rifle hoping for it to shoot about 2 moa although not exactly expecting it. I figured on putting a micro red dot on it and it would be a pretty handy package with the folder. As it is, it's heavier than expected weight has me second guessing using it as a "light-ish weight carbine" with a red dot and debating adding a magnified optic to take advantage of the accuracy. The issue there is that any of the optics+mount that I'm considering (1-6.5, 1-8.5, 3-12 with offset dot) all push the weight of the whole package north of 10lbs. Possibly I might change the "Galil" folder for a buffed tube and folding adapter to cut weight (if that's the case) and improve cheek well. I'll most likely run it as is for at least another 500-1000 rounds to ensure that it runs reliably and work out what other mags it will run well with.
