Hi fellas,
I've had my M305 since last summer with no issues at all, but now am looking for some guidance. I bought a choate collapsible stock off of EE and am having trouble as I install it. While the reciever is a bit of a tight fit into the stock the bolt behaves well cycling, but that changes once the trigger pack is in (very difficult to get the guard all the way down and in), as then the bolt becomes sticky and difficult to cycle. In addition magazines become difficult to insert and remove. Has anyone had similar issues? Any help would be much appreciated.
Thanks
 
You may have to file the stock down where the trigger group goes in if its fitting too tight.
The archangel stocks are the same , a little fitting required
 
Thanks i was considering taking my dremmel to it but decided to stop by here first. Do you think that would also explain the magazine fitment issues?
 
If possible when removing material use a flat file. The heel of the receiver should contact the stock and there should be an air gap under the receiver rails. One accurizing technique is to shim or build up the stock to achieve that contact. Likewise, the trigger guard should contact consistently across the bottom of the stock without any gaps.
 
if you remove material from the trigger pads at the front of the trigger area , be sure to remove the same amount from the rear pads of the trigger group.
a caliper to measure how much you are removing is an essential tool for this job.

be sure to do the M14 function test to ensure safe operation before going live. Visit the M14 FAQ section for more info. Stock fitting threads are in there too
 
Check the top of the stock, under where the receiver sits (Specifically under the op rod shelf). That needs to be clearances for the Chinese receiver FIRST, before removing material where the trigger pads sit.

You wouldn’t believe how many stocks I’ve had to add bedding material for the trigger pads after customers have removed material in the wrong places......
 
There is a set distance required between the trigger group and receiver and if the two are too close together the hammer can’t get out of the way of the bolt and will hang up on it. Since the magazine release is built into the trigger group it’s “height” matters as well and it needs to be low enough so the catch can get past the lug on the rear of the magazine.

I had a similar issue when glass bedding a M1A into a new Mcmillan stock. The rifle has a rear lug which I had drilled and tapped and added a rear pillar and screw. Because of this the gun no longer relys on trigger guard clamping pressure to hold the receiver into the stock, so I relieved the underside of the stock to the point that the trigger guard could be closed with only enough force to keep it latched and no more.

First thing I noticed was the bolt was difficult to manually cycle to the rear and would hang up on the hammer nose. The magazines wouldn’t lock up either. Basically the whole trigger group was too close in the vertical sense to the receiver. I ended up re bedding just the trigger group a little further away from the receiver and it now functions fine.

There is actually a specific distance required which I can get from the shop manual but that’s the basic jist of what I encountered.

Try cycling the action and seating a magazine with the trigger guard half closed.

Thanks for all the responses guys, I know it's an old post now but figured an update was due now that things are a bit calmer on my end. This thing is gonna be long, I am adding this to assist any new owners of a choate stock since I had trouble finding info when I first got it.
I used all of your advice as well as some stickies to try to figure out the problem area but it was CGN user jonh172 who PM'd me with a remarkably accurate diagnosis based on what I had written here plus some texts and a call.
Basically the oprod was too big for the stock and was rubbing against the bottom of said stock. A significant amount of sanding had to be done to the area of the stock through which the oprod travels. In addition to to this some sanding was done to the area where the trigger group pads touch, and some material was shaved flat with a file on the top of the stock where the heal of the reciever fits (different angles, flatter compared to the M1A the choate was designed around).
Once the oprod was freely cycling with no spring or bolt I reassembled and did the functions test that 45ACPKING was kind enough to remind me of. I'm very thankful he did because the hammer followed the bolt; the disconnector didn't engage. With some additional trigger pad shaving and even more oprod-area shaving the rifle passed the function tests consistently and yesterday I took her to the range, 20rnds Hirt down the pipe with no hiccups.
Again thank you all for your contributions especially Jon, who is an excellent example of this communities good will . If anyone has questions feel free to ask away and I will try to answer
 
Very kind words Ben thank you!

Lots of helpful people in this community and it’s a treat to help those such as yourself who are not only very nice fellas, but those who are excited about the platform, wanting to keep the wood and steel tradition (fancy word for obsession) alive!!

Post up some pictures when you get a chance :cool:

Jon
 
I don't offer as much advice as I used to but I do very much enjoy seeing new m14 owners who utilize the archived information and approach the rest of us with an open mind.
It's also really cool too see so many gun nuts that learned from us (and others) , now at their own higher level of understanding and able to help guys out.
