Marstar M14 Aluminum chassis
- Thread starter mag627
- Start date
Stock and grip are both from Command Arms (also called TDI). The stock is kind of hard to come by in Canada, and was bought for a future AR-15 build I'm doing. I dissassembled the rifle to take the pictures as the barrel is going to Dlask for a 18.5" chop.
If anyone is interested I have an extra AKM chassis that I'm looking to get rid of.

Take payments???? hehehe
I am maybe/possibly/perhaps considering selling or trading off my camo painted AKM chop mod stock, as pictured above.
Anyone interested?
Cash is not really a priority right now, but maybe an interresting trade??
The stock would be available with or without the YHM tube butt stock and AR 15 full length buffer tube that hides inside the YHM butt. I know most people prefer a sliding stock on their AKM, but the chop mod balances better for me with the YHM tube stock.
The chopmod with YHM butt weighs in at 5 Kilos with a shorty M14, with comp, scope and an empty 5/30 mag, and it balances WAY better than the regular AKM stock. I tried two different Norcs in it last weekend, using iron sights and a 4X scope, and shot off about 40 rds ...
as 5 rd strings, mostly to see what ammo it preferred.
With one norc, basically a stock shorty, it was totally reliable, but it shot about 2" -3" groups.
With the other norc, highly modified with GI bolt, round op rod spring guide, etc, it shot one group that was sub-moa [ Federal 150 gr hi shock SP ], but there were a few stoppages as the extracted brass got caught between the rail and the receiver.
This is a warning to those using the GI bolts and GI extractor/ejector and spring ... sometimes you have to clip a few coils off of the ejector spring to get the extraction just right with a low mounted scope rail. This also occurs sometimes with the new style solid bridge ARMS mount.
So the AKM rail will probably have a meeting with Mr Milling machine, to groove out the right side to clear.
Any one else have issues with their AKM rail biting the brass on the way out?

Depending on the price I would be. I am looking to get out of my USGI and UTG rail setup on mine and go for a more agressive tactical look. Interested in my stock as a part trade? PM me to see if we can work something out.

Hey guys,
I have had my Marstar AKM stock for 3 years now. I got it from a Duke over at the EBRSopmod forums, who just happened to lived in the same town as me.
I was actually waiting for a Sage Mod 1 stock, but I then I saw the AKM stock in person and Duke gave me a kickass price, so I could not pass up this deal. I figured I would give it a try and see how I liked it, eventually I found out she's a keeper.
I had to make a lot of mods to the stock work though.
- The Marstar supplied Gas Block fit dam tight, took a couple of good whacks with the hammer to get it on, but I can't really complain because it eventually went on and I was able to properly line up the holes to pin it in. I guess this is not really a problem since tight is good.
- The Springfield M1A Receiver would not fit in the stock: this was fixed by filing the inside of the stock until it would fit. It is still hard to get her in, and I can file it more to make it easier, but I like I said, I like things nice and tight if you know what I mean
- The bolt was hitting the back of the AKM stock. I notice this after a range session. If your oprod spring is worn this is more likely to happen. I fixed this by relieving the back of the stock (basically took out a lot of metal) so it would no longer hit. The relief cuts are ugly, but hey it works and also it is on the inside where you can't see it I also replace my Oprod Springs as extra insurance.
- The scope mount sits way too low and this will sometimes cause stove pipes (just like on those M14 ARMS scope mounts).
One of the main reason I bought the Marstar was because it came with a scope mount so I did not have to pay another $250 for those SEI scope mounts that don't really work anyways.
I was very disappointed when the stove pipes occurred, they were infrequent, about one out of ever 40 rounds or so, but they bugged me enough I had to do something about it.
Replacing your extractor is one fix but as your extractor gets worn, this will re-occur and get worse and worse. M14's are known for weak extraction sometimes. For the most part this is not a problem because of the open bolt design, but with that low scope mount it will be a problem, if not now then later. I fixed this by ditching most of the Marstar Scope Mount, I hack-sawed the mount only keeping the part where the rails meet the Receiver. I put on a American Defense Extended AR-type mount and mounted it backwards (got this idea from the Fongman over on the EBR boards). This completely got rid of all the stove pipes.
- The cheekweld sucked as the buttstock sat way too low to use with a scope. This was fixed by getting a CTR stock with a cheek riser and now cheekweld is perfect.
- You can't use Iron Sites with the Stock. I have not corrected this yet, but I plan to soon. Will be taking it to a machinist friend and have him bevel down the whole length of the top rail just enough to use the iron sites.
- The Rails are out of spec, they are smaller in width than true milspec. Nothing you can do about this other than buy parts that clamp down lower than Milspec, which I did.
- Shw was a pain to clean. You have to take off the scope and scope rail to clean her, but once you do this you have to re-zero. However this problem was corrected with a ADM mount. Cleaning is so much easier now, don't need to remove the scope mount, just need to take off the top rail cover with scopemount still in place, and the rest cleans like a regular M14.
Now she is a perfect shooter and shoots just as good as my SuperSASS (as far as accuracy goes). The stock does not really free-float the barrel but it is just as good as a free floating barrel. The Barrel is now screwed to the stock making it one (via the Marstar gas block), just like a custom bedding job. Before the Marstar stock, my M1A was only sometimes accurate, depending on how the action shifted around in the USGI stock.
Here she is with my Armalite AR-10 SuperSASS. I am allowed to use 20 round mags, but for precision weapons I prefer 10 round mags as they give the rifle a cleaner look, and also they allow the rifle to sit lower.
This is what she can do for 10 shot groups at 100 yards even during a bad day with 20-25 mph crosswinds. I could not keep the rifle steady at all, as you can tell from the high and low shot. Despite the winds though, you can see she still did pretty good.
If you are wondering what I look like, here is me at my local range in the Metal Gong Section (200-900 yards).

The scope mount is from American Defense Mfg. It's basically the same thing as the Larue SPR-E and it holds zero as good as anything out there. Got 3 of them. One on my AR-10, my Bushmaster .450, and the M1A.
