Marstar m14 AKM chassis

I know but some rifles shoot better when in more rigid stocks that have a better fit. Like if you had a Chu wood stock that has become soft. Many EBR users boast improved accuracy after moving theirs from their usgi stock into the EBR. just wondering if this was the same.
 
Blackfeather stocks are supposed to improve accuracy as well with the op rod guide-a-ma-jig thing in it.

The only M-305 I've ever shot was my rifle in a Troy MCS. It shoots a very consistent 1.5-2 MOA. Some were MOA or very close, but not enough to say with confidence that I could repeat it.
 
I have had one for 4 years. It will make it a little heavier, I took the side and bottom rails off. I also cut the top rail as I did have some stoppages from brass bouncing down and catching the charging handle. I found it more accurate than the chew wood stock. I have hunted it and recently put a shorty in it. I was going to sell it but changed my mind as it is one of my never sells. If you got a good price I think you should be pretty happy with it.
 
Here are some notes that may be helpful:

1.] Both the SAGE and the AKM M14 stock designs require the removal of several upper hand guard/lower stock screws for detail stripping and cleaning.

2.] As mentioned by H20, the Sage and the AKM use a "free floating from the op rod guide forward" barrel to stock retention system which will help improve accuracy.

3.] The AKM stocks, while nicely machined, are made from a soft alloy, and the removable scope mount rail over the receiver is not mounted solid. Some AKM owners have found that some grinding of the stock bedding is required with some receivers to get a decent fit, and some have found that shimming under the tail of the receiver is required to get best accuracy. But all in all, the AKM is a viable M14 EBR stock which has sold well in Canada, but which now seems to have ceased production.

4.] Of the 2 stocks I mention, I believe the AKM is the heavier.

Here are a few photos. I`d be very interested to read what the stock weighs. If you get a chance, send a photo of the chassis on a weigh scale to info@m14.ca

Somewhere I have weights and such for the AKM vs Troy vs Sage I'll see what I can dig up.
From my conversations with John, the founder of marstar, the company making the chassis went under or something. The CNC files were offered to marstar for a price and John declined. I think, but don't quote me as I shouldn't speak for marstar, but the amount was in the 20,000 range.
But then there is tooling up.... And that ain't cheap.

Overall a nice chassis.
It does "enhance" the rifle's accuracy potential due to rigidity of the material and due to it's bolted in oprod guide.
Much like other aluminum chassis using "similar" features, ie black feather and sage.
I'd keep it for sure. ;)
 
I've owned 2 AKM chassis's, not bad I guess, I have no other systems to compare but the metal did seem soft, the scope mount was a good idea but poorly executed. The rail worked good for red dots but not worth the added weight IMHO. I'm pretty sure the AKM was based on the sage and the blackfeather designed their stock around the OP rod guide mount used on the sage and AKM.

To correct Activeshooter here and for posterity and clarification, we designed the M14.ca Blackfeather RS operating rod guide (ORG) from scratch. The ORG we built was newly designed in 2012 and tested on approx. 11 M14 rifles for optimization and procedural fitment. Originally, it started as a two part oprod guide. That part and process took 2 months to falter. Then, we started again. The new ORG took 2 months to prove out.

So, the new Blackfeather RS ORG is:
- a built-in barrel tensioner which allows adjustment for load development (or it can be locked in place without tension).
- attached to the stock is via one take-down bolt (which allows you to remove the action from the rifle stock easily for maintenance and cleaning)
- not affixed to the rifle stock (as opposed to AKM or Sage) (supported with an internal butressing)
- designed with a built-in operating rod lubrication detent circumferencing the rod that allows you to pack the ORG with grease
- the largest and thickest ORG made (it has the largest surface bearing area of any ORG including the fat ones built in the early years for National Matches)
- seated on a large-surface-area, steel anti-wear plate to avoid fatiguing the aluminium rifle stock at the base of the steel ORG
- built with 4140 heat treated and stress relieved steel
- similar to the original M14 take down, with the addition of only one extra bolt (remove trigger group, remove bolt)
- better at maintaining zero after re&re of the action from the stock than the SAGE or AKM chassis (because they require multiple bolts for removal of the action from the stock)
- able to swap barrel and receiver groups easily with minimal disruption to zero (short barreled CQB rifles and long barreled DMR, for example if you own more than one M14).

For those interested in our Engineering and Design Considerations of the BF ORG, please see this PDF file.

To continue the AKM discussion, my only concern with the AKM would be replacement parts but you may never need them. Check it over and ensure the installation is done right. Cinch down the fasteners to the recommended torque and loctite what you can. I have seen an M305 in an AKM group very well and they look damn good. You`ll enjoy it.
