MDI SLR receivers come loose.

after reading all the drama on multiple post on the SLR... my spot came up on preorder and i just canceled. Way to much problem for a 1000$ receiver set.
I am a fan thoroughly impressed by mine. 200 rounds today and no lose takedown bolt like some have reported.
 
In theory, the nord-lock would be the ticket, but the external diameter of the washer wouldn't fit in the bolt hole in the receiver.
There isn't enough 'meat' left to take the hole out large enough to allow the use of the washer.
I guess it's back to purple Loctite, +/- split washer.....
Sigh......

Perhaps try a star washer with a thin aluminum washer? Place the aluminum washer against the receiver side to act as the sacrificial surface.
 
I am beginning to think that a number of issues is with owner error and not the product.


Doubt.

Multiple people have had the same issue. Im probably the person with the most rounds down range on CGN with the SLR at this point. But I might be wrong.
 
For instance. Mine went together no problem, apart from the trigger, which I was prepared for going in. Lucky I had a stock r-15 trigger kicking around, which is actually pretty good. My parts all went in as to be expected, I r mechanic though so I’m pretty used to this sort of thing. Got my headspace checked out thanks to Tier One Armory, thanks again for that. Mine ran an assortment of ammo ranging from 43gr to 55gr, factory and my handloads today with no malfunctions. It was a terrible day for accuracy testing, gusting ever changing wind so I just tried a bunch of combos to see what worked. Everything did, the 43gr shot poorly, not surprising but the 55gr stuff showed promise, going to try some 75gr I made on a better day. The fit in finish is good, I’ve seen nicer, not quite ATRS level, but much better than BCL. Most of my mags fit, a little tight in the upper on some, had some C-prod. pistol mags, an IWI pistol mag, and the factory R-15 mag, couple were a bit tight, the R-15 mag drops free. Really my only complain is that I wish I had it this summer. Got plans to go out looking for coyote tomorrow so we will see if it gets fired tomorrow or not.

Good write up as I agree with your post. My metal mags are a bit tighter but I am sitting down and repeatedly pulling them in and out to create some wear. I prefer tight over sloppy anyways. Also I like how tight the upper and lower fit together because I despise rattle bucket AR’s.
 
that's a great lookin rifle Uisge did you have the dreaded loose bolt problem? I'm around 400 without that problem. I have only ran 55 and 62 gr so far
 
If you want to run a nord lock style washer and its to big.
1. place the nord lock on a different bolt with a nut same size head as your slr bolt.
2.Place the threaded nut side in a 3/8 drill.
3.spin in drill against grinding wheel untill sized.
4.Use your nord lock.
I have had one on my slr from the beginning seems to work fine.
good luck.
