Hi I am still having problems with my rifle, went to range this weekend shot about 60 Rds one round got stuck tried to pull charging handle and bolt would not budge had to take rifle apart and pry bolt back with screwdriver and mallet. what would cause bolt to stick like this?
You’re going to need to tell us alot more.
Ammo used, mags used, did you lube the gun before you went, etc.
The ammo I used was M855, mags were Magpaul Pmags and D&H Cproducts and I lubed rifle last week. Dont mean to ask stupid questions does chamber and bolt face have to be lubed also?
The only stupid questions are those that go unasked… Now for mine.
Did your Stag come with an operators/users manual or guide of any type? Does it cover cleaning/lube? Did you clean the rifle before you went to the range? Was this your first trip to th range with this weapon?
I’ll assume there was a live round in the chamber while you were prying and hitting…
Not busting your balls just trying to get to the bottom of this.
The only instance I can think of where someone’s carbine got locked up like this was a situation where they popped a primer and it lodged in the cam pin area which prevented the weapon from cycling. After you got everything freed up, do you recall if the case was missing a primer?
No upper did not come with any manual. I cleaned rifle when I fired ti last week 2nd time to range first time had FTF, FTE issues gunsmith at range said it was proably due to ammo I was using Remmington .45gr JHP
No there was no live round just empty beass casing.
Primer was intact.
I would say to shoot another 200 rounds or so through it and see if it happens again.
That’s what the plan is gunsmith gave me a chamber brush to clean chamber good and give it another try
Something’s definitely screwed here. Can you elaborate on your initial problem. Were you able to retract the charging handle at all, did the bolt partially retract and then just stop? Where did you insert the screwdriver and what did you pry it against?
When I think of being locked up tight, I picture the bolt still fully engaging the lugs and the reason you can’t retract it is that there’s something impeding the cam pin which is not allowing the bolt to disengage. If that’s the case here, I can’t figure out what you pried against with the screw driver, did you just pound on the charging handle? If the bolt rotated and disengaged then you would expect the whole BCG to just slide to the rear. If it started to retract then stopped, what caused it to stop? I’m not doubting what you’re saying, I’m just trying to picture in my mind what could have happened.
Also, I’m assuming you didn’t end up with a double feed or a bolt override that jammed things up, correct? No unfired cases with big gouges along the body?
when I first started shooting had a few minor problems with FTF bullet would get stuck at an angle halfway in mag and halfway in barrel on last mag I shot fired one round squeezed trigger and nothing tried pulling charging handle it would only move about an inch or so I took it to the gunsmith to have him look at it.
gunsmith took rifle apart and pryed on bottom of bolt to get it open, after that I put rifle back together and pulled charging handle it was not sticking after that
Is the lower also a Stag?
Yes both upper and lower are both Stag.
The only time I’ve has something like this occur to me was when I was shooting Wolf ammo through a barrel whose chamber and bore were not chrome-lined. Is your rifle chrome-lined?
Yes barrel is cromed lined and ammo I used was M855
Sounds like it may have been a bolt over base malfunction where the magazine spring is worn or underpowered and doesn’t present the next round in time for the bolt to impact the rear (case head) of the cartridge. Therefore, the bolt rides over the round and impacts it on the side somewhere, pushing it partly out of the magazine, and lodging it with the bolt out of battery.
My suggestion would be to isolate the culprit magazine and shoot some more using different mags to see if it happens again. If not, you may have found the problem.
Some questions that may clarify, where was the cartridge when it “jammed?”, in the chamber, part of the way in, touching the feed ramps, etc. Also, how many rounds were in the magazine when it happened?
Shooting M855 and had a hard FTE, anyone wanna bet that a chamber reamer will end up removing material?
I don’t think is a chamber issue, although it could be a contributing factor. This sounds more like a mag or lost primer issue to me. Tight chambers don’t lock things up solid like this yet still leave primers intact. Unless the previous round left a primer floating around somewhere that tied things up, but this sounds like a very mechanical, “wedge” issue, the wedge either being a partially fed case or a lodged primer.
