Out of curiosity, anyone here had difficulty installing a TROY MCS?

I know some guys have trouble getting the trigger group to fit right so that the hammer doesn't follow. I don;t have that problem, BUT...

I've tried the chassis I have (an early MkII that still has allen screws) and with the rail installed, the upper will not seat low enough into the chassis to allow the take-down pin to close.

I think the upper block that fits into the rear sight hollow need to be machined a few thou so the back of the rail will seat low enough - anyone else had this problem???
 
I managed to get mine to work. I'm not sure if my Troy stock was out of spec, or if the 2009 Poly receiver I'm using is slightly different than the USGI (presumably?) drawings Troy would have used to build their stock.

The issue is that the machined block that fits into the rear sight recess was about 30 thou too tall at the front end. You can't machine the whole thing because of the fixed pivot locations for the rear sight screws and the location of the rear action pin.

To fix it, in the end, I had to clamp it into my mill with a 1 in 10 angle and machine a slight angle at the forward tip. It now fits perfectly with only about 3 thou of compression to close the action pin, which is just enough tension to hold it solid without warping the top rail when you close the pin.

Here's some pics in case anyone else hits this problem with a Troy stock on a Chinese receiver.

FWIW, I tried the stock on a 2005 Noc and the same dimensional issue was also present.

After machining, note all the machining was done in such a way to be invisible when the stock is assembled and the screws were re-loctited:

And assembled for trial fit:

Not bad, huh?
 
Thanks for the post. (I like it, but in black with an Ace folder, no bipod, no foregrip, with irons). Have a look at this one:

Yeah, the beauty of this system is that the stocks are interchangeable, foregrips are removable, etc.

The bipod on this one is only there to hold the rifle up for the photo. If I keep it, I'll get a better adaptor. The present one is a cheap chinese bipod stud adaptor.

The foregrip is not needed for most shooting, but if you do snap shooting, which is what the in-line stock was designed for, then it becomes almost essential to improve control.

The Magpul ### in your photo is basically the same thing with different ergonomics.

I don't have sights on this gun yet, but I'll probably put on Troy BUIS if I end up having room. The gun is getting Laupold MkIV Aluminum rings and a Leupold VX3 3.5-10x50 with M1 turrets and mildot reticle.

As for the color, I got the stock new in box off the CGN EE because I couldn't find one new in stock anywhere at the time. The one Ibought was FDE because that's all that was avaialble, so I bought all the parts to match the stock. It looks pretty decent in person, actually.
 
By the way, the rifle as built above has the following specs in case anyone's interested:

Receiver: 2009 Polytech
Op Rod: USGI SAK
Bolt: I have a USGI HRN bolt robbed out of another M14 for the mock-up, but it will ultimately get a 762mmfirearms bolt in a few weeks
Muzzle Break: Dlask Bull Break in 7.62
Barrel: 2007 Norinco shorty
Gas system: 2005 Norinco
Pistol Grip: Magpul MIAD
Stock: Magpul CTR
Tube: Hi-Standard milspec
Op Rod Spring Guide: Marstar
all springs: Chrome-silicon USGI springs
foregrip: Tapco
Pannels: Magpul FDE on the sides and black Magpul ladders on the underside
Bipod: Harris
Trigger group: 2009 Poly housing with Breda hammer, Beretta trigger and Springfield Armory USGI pins.
Bolt Stop: Smith Enterprises
 
Hi guys, two questions. The first, is the Troy MCS (or SASS) system available though any distributors in Canada, and secondly, does the Troy SASS system change the status of the Norinco M14 from non-restricted to restricted? Yes.. I'm a noob.. but I'm looking into purchasing an M14 and I'm quite interested in the overall Troy package.
 
The status is NOT changed. No dealers carrying it anymore that I know of. Fabsports USED to sell them before they got into selling SAGE.

Welcome to the world of chinese spec rifles -
The Troy is in spec -

Chinese specs -

I have even had Norcs with the stripper clip guide slots at different angles -

Thinking about doing a Troy MCS build on a Norinco M305. Do you have to machine the MCS, or can you do some light filing? I don't have access to a mill. Would this be something better taken to a gunsmith?
 
have not had to machine any of the troys i have installed to chinese rifles. I've done about 15 installs to date.
other's may have different experience.
 
Also, e-mailed Fab Sports about ordering in the MCS and they said it wasn't possible. Any other Troy dealers that could hook me up? E-mailed Arms East a couple days ago and haven't heard anything back.
 
Of those I've now installed (5), two needed machining to fit 2009 vintage Poly receivers. The Norinco receivers seem more consistent?

On one, I had to mod the part that sits in the rear sight area, on the other I had to skim a few thou off the rear trigger housing pad area to get the TG to seat anough to work with the receiver in the stock.

Maybe I just got unlucky with two slightly out of spec receivers? Dunno. Both installed flawlessly in a Sage EBR test chassy???

In any event, in both cases I got the chassis to fit with what I would consider very milling machine minor mods to the stock.
