MDI SLR receivers come loose.

These receiver sets were over hyped from the start, however I suspect that loctite would solve the issue. It just sucks because with DI you have to clean the bolt and receiver more often which means applying loctite every time you clean. It seems they have a few teething issues, and hopefully they will rectify them with customers and improve their design from feedback.

Loving my WK btw, but they have had some minor teething issues as well which are rectified at light speed from kodiak. I would like to see an SLR first hand.

So youre saying that its a well conceived system? That its a feature that you have to loctite a bolt every time you need to take down the rifle? Do they pay you lol The 'stop whining and find a solution' schtick is tired and old. The solution is to stop supporting a compamny that makes a poorly thought out product, and by advocating against them I am fulfilling my moral duty to any other consumer who would consider buying such a #### product i.e. more than youre doing.

I at least bought the gun, put the money in to make a decent build, tested hundreds of rounds through it. What have you done?

Its a s h i t e product design. Just rushed out to sell as many as possible on that NR AR hype.

You don't have to clean a DI rifle any more than any other semi auto. I've run my AR's well over 1000 rounds without cleaning and all they needed was a drop or two of oil every now and then. I've never actually had an AR fail to function from being dirty, only from not being lubed enough.

I have buddies that run an entire summer of 3-gun without cleaning their DI AR, just lube it before the shooting starts, play all day and worry about it again next weekend.

I doubt that anyone other than MDI fanboys would argue that it's not the best system but the solution sounds pretty simple and there's nothing MDI is going to do about it now. I realize that there was no way to predict the bolt coming loose while firing but you did agree to buy this receiver set knowing that it was held together with a bolt. They were quite proud of their upper/lower dovetail type interface and everyone liked how it would create a no wiggle interface.

So you're stuck with it unless you decide to sell it so may as well make the best of it and throw a little locktite in there and get back out shooting.

Other than the bolt coming loose have you had any other issues? Was your rifle one of the ones with tight holes? Crappy anodizing?

Once again, this is exactly why I refuse to jump in on any pre-sale of any kind. Until I see what I'm paying for I'm not putting my money on the table.

The hands down, best by a country mile, no make that a light year locking washer I have ever witnessed is a nord-lock. Amazing design. I have a 5/16 nord-lock on a stud with a wing nut. I can gently tighten it with 2 fingers, and you'll need pliers to undo it. You have to see it to believe it!

That may be a little excessive for this application, I think beltfed's idea about a stud and nylock nut would probably be the easiest if a little blue locktite doesn't hold the original bolt.

No i didnt say that.
No they dont pay me. Hah.
Jrc uses bolts. Yes i loctite them evey time i clean it. Its an expensive process. Sigh....
The solution for you, if we go by experience, is to whine and b1tch.

Ps, my receiver will be an atrs. Always has been. Always will be.

Do you see people whining about jr carbines rattling loose? Because they all do, eventually.


Hey if its so bad it should sell on the ee for a 50% loss in a heart beat.

Sounds like a poor design.

I believe you mean, inform others that the $1000 product they bought is prone to a major issue and actually poorly designed. I reached out to MDI. They said use a washer...I am informing the firearms community of my experience. 'whining and #####ing' as you called it allows people to know what theyre getting in to with this product.

Whether people want to speak out about THEIR defective products or poorly designed products is not my business. I only fulfill my moral duty to speak out about mine.

You on the other hand have done nothing but add snark to the conversation.

Real productive.

Why is using locktite when you assemble it an expensive process?

50% loss? You mean 20% gain don't you? This is the CGN EE we're talking about and a new to market non restricted semi auto thingy? Yup, should sell for more than retail to some desperate guy that is convinced this is the greatest thing to ever hit the Canadian market and can't wait another month to order one. Probably be someone who has to put it on the credit card and can't afford the rest of the parts or to buy ammunition for it but they have to have it.

Agreed, my next will be another ATRS product, the SLR never interested me at all and unfortunately the issues people are having with them are no surprise to me after the gong show we watched just to get them to market.

Nope!! That would be a helicoil and from the looks of the ones I have seen, a very poorly installed one at that. Why they would not have threaded in a proper insert is beyond me. Helicoils are very much a 1970s backyard style fix compared to what is available today from many fastener companies.

Hotsoup Do NOT use Blue Loktite as it does set up and you will require heat to get it to let go. Purple is the correct type as it is not a structural locking compound like blue or red is.
There are lockwasher that are essentially a flat washer that has teeth on both sides. I would think that bonding 1 to the upper to keep it in place would work as not damage the aluminum as beltfed has mentioned. There is a proper name for those lock washers I just can't for the life of me remeber it.

Glad I held out on the SLR and went with the M.S.. I saw my M.S lower today and all I can say is WOW!! Can't wait for the rear pins to be available and I can pick it up.

Really? That just took my opinion of this to an entirely new realm of WTF.
I remember them back in the 80's, strip a bolt? No problem, just push this in there and it's good as new, lol. I didn't even know you could still buy them.

I'm still hesitant to drop my money on the ATRS one, not because I worry about what I'll be picking up when it's ready but worried that the RCMP lab will pull some batcrap crazy classification and I'll end up with a $1000 restricted receiver set.
I know, chances are very unlikely but I really don't trust them after all the weird crap they've been pulling the last few years.

I don't really agree that it's the price we pay for NR, if that was the case we wouldn't have the WK180-c for $1000. What you're paying a premium for is the top quality CNC machining and 7075 aluminum billet as well as a long list of other production expenses, unfortunately these don't seem to be living up to the top quality bit.
These are pretty much the same price as the ATRS receiver sets (even their restricted receiver set is almost $1000 and has been for years) and while I agree that they are expensive and it's a lot of money for a stripped receiver set I don't think they are overpriced or that we are being gouged, these are not and never were advertised as a budget or entry level product that everyone could afford. If someone wants budget and affordable they need to settle for something like the WK180-c and not a SLR or MS build.

It's hard not to compare them to a forged set but it's not fair to compare something that is a mass produced forging to a small run CNC process, CNC is going to cost more regardless of it's legal classification and anything made in Canada is going to cost more due to our high pay rates here.
Hard to produce a product for $500 when the labor costs are going to be $200 per unit since they still need to be paying a skilled tradesman to sit at the CNC machine for 2 hours while it carves out the receiver and then another well paid skilled worker does the finishing work and handling before it's sent off for coating or surface treatment. There's a lot of overhead for a shop in Canada as well, unless they are operating out of their home garage there are a lot of costs just having a space which I'm sure you can relate to with your own monthly bills for your home.


.

A split washer would probably gouge the aluminum receiver when you tighten it down, would probably hold but it will make a bit of a mess after you've tightened it a few times.

Lol where are u getting this from ?! Are u a machinist ? A lot of the button pushers in these shops are making $18 starting XD top quality CNC machining?! Its a CNC people. They are all capable of machining to a 10 000th of an inch if it's written into the code.

Ultimately the WK 180 is machined the same way, employing "skilled tradesman" in a machine shop located in Canada.... except for the SAME price tag of $1000cad they can supply to their customers a fully functioning rifle with all the components, kodiak defenses profit, and Wolverines profit all included. That alone undoubtedly and unquestionably proves that the SLR is marked up a lot and its pissing many people off that they couldn't at least live up to the excuse that its "super high quality"

Yes but a jr is a fully complete and functioning rifle for the same price. It's easier to look the other way for that one.

Lol, I have been accussed of overkill in the past! However, these lockwashers are an engineering marvel and do not chew up the mating assemblies like other lock washers.
Best regards
 
So anyone in to do a preorder from me on a new NR firearm?

I have 0 CNC experience, am what I would consider an above-average amateur gunsmith, and have a passion for firearms.

I won’t say when I’ll be complete building it, or even designing it... but if I put 3 letters ‘eta’ in front of it, that takes care of that issue.
When I run into trouble about questioning the length in time it’s taking, or asking for updates - I’ll refer back to a common phrase of ‘working on it being perfect, thank you for your patience’.

So who’s in? I’ll only charge... ahh, let’s say $1000 for the receiver set.

Anyone? Anyone at all? Deal of a lifetime.
/sarcasm
 
For what we use them for this is a fine NR semi auto product. I like the finish and tight tolerances which will eventually loosen up with use. I do wish they had pic rail T marking tho. The takedown bolt is a aggravation but I rarely strip my ARs for cleaning as I just oil and go which is enough for most good black rifles. Again for what we use them for repeatedly stripping this receiver set is not necessary. Having said that I do like the MS which I will be going after.
 
cant use a stud on there design. it has to slide apart to come apart so a stud aint gona work to well. the lil washers you want to try are called a star lock or center lock washer. I have 300 plus through mine and it has not come loose on me. maybe you need to use a bigger wrench?
