The box portion of mine will stay put with a little tension when installed. I haven't broke it down since I got it back from mossberg service. They nicked the stock in several places and I'm not real happy with them to say the least!!! I called mossberg after I got it back and their response was that was as good as it gets with my firearm and that it was functioning as designed when it left their facility. Maybe That I was trying to feed the rounds too quickly and that was the root cause of my complaint. I say b.s.

do you try to drive the rounds in to fast like they say?? i have seen rouns pop out of even the finest of the weapons when they are driven in to fast. i had to get on a guys but one time when i had a old .22 bolt action man he was slamming that thing back and forth like i don't know what running them rounds in and out . i finally got tied of it and said man you break my gun and i'm gonna break yo you know what! a bolt action rifle should be smothly pulled back and slid forward unless it's an emergency that you depreratly need to slam the bolt back and farword. now i am not saying that is waht your doing i'm just asking if your maybe going alittle to fast .

No matter the speed of chambering. I have modified the follower with a few strips of duct tape along the sloped part in the center of the follower.
this seemed to reduce the problems except the last round issues. I then removed the follower and laid in a 1/16" layer of epoxy and sharpened the angle of this slope to put more force on the upper radius of the round to get the round to positioned deeper into the reciever/ bolt race groove.
I noticed the follower was loose laterally and appears to be too narrow for the box part of the magazine. I then tweaked the sides of the magazine box to tighten this fit and reassembled the firearm. It has chambered and ejected all 4 rounds a dozen times now without a jam or auto-eject issue.

Could you post pictures? On another forum members are having the same problem. see: mossberg 100 atr feeding issues - Firearm & Gun Forum - FireArmsTalk.com

It would be great if we could share info on this. -AimHigh

I am just not sure how some can feed fine and others don't. If it was a "design flaw" you would think they all would have problems. I no on other forums of guys having problems only after they dissasembled it. The post on other sites about the bolt coming apart don't make much sense to me either. It is a pressed bolt, but if the tolerances are tight a prss fit should never come apart. Heck wheel bearings in a lot of cars are press fit and they don't normally fly apart sending wheel down the road. I do think it would be cheap insurance for Mossberg to put a small roll pin or something as an added mesure of safety. In other post regaurding the bolt there are concerns of it flying out and hitting the shooter in the head, but I am not sure how if the bolt handle was down in place it should prevent the firing pin assembley from releasing. I am thinking about getting another one in .243 for coyotes because I love my .308 so much. I just don't understand the inconsitancies people are having with the ATR.

I agree with you on both counts. A press fit should work and the bolt handle being "down and locked" should prevent the bolt being blown back in your face. The problem is when these first came out they were press fit and brazed (according to the American Rifleman write up). If there is a problem with the lugs not engaging fully on even a small percentage of the rifles Mossberg needs to re-look at their manufacturing process a la Ruger and the SR9 and their new .380.
The issue with the last round feeding (at least for me) is that once the round (.270 Win in my case) clears the right side of the bolt rail as the round moves forward the follower is popping up and throwing the round out of receiver. I called Mossberg on this over a month ago. They said they were sending a new follower/spring assy. and magazine box. Nothing yet from Mossberg. I think the reason some have trouble and others don't is that tolerances on all these parts are pretty loose (as compared to chamber/barrel dimensions etc.) and the follower spring can seat in the stock in various positions. I have tried numerous things, including putting a dab of silicon in the stock to hold the spring in the molded grooves at the base. Still no help. Bottom line: This was a $250 gun I bought at WalMart. I knew that at this price I wasn't getting a Kimber, T/C Icon, or even a Remington 700. I can live with loading 4 rounds and knowing that I can chamber and fire only 3. For hunting purposes - no problem. I'm just trying to make the best of what I have by seeing if anybody else had a similer problem, and how/if they fixed it. I wish you luck on the purchase of your .243. You may wish to buy it from a gun store that has A-Zooms, Snap Caps, or dummy rounds and cycle a few through the chamber. I didn't do this at WalMart - lesson learned. -AimHigh

Yeah that really sucks. I personally wouldn't give Mossberg a muligan because it is an inexpensive rifle. The thing should still feed rounds and perform the basic functions of a rifle. I went up earlier and looked mine over real good, put 4 rounds in the mag and 1 in the chamber. I then cycled the bolt real slow, med and fast and it worked great. I would just not be very happy if I had your problem. When I saw the new adjustable trigger, I thought I would like to get a .243 maybe a super bantam because I have a 5 year old and maybe she could use it in a few years. It really makes think twice to hear these problems some people are having. I am waiting for the new Marlin XS7 short action to arive on shelves as I have always wanted a 7mm-08 and I belive they are gonna be available in .243 also.

Hi. Sorry to dig up a thread that hasn't been posted in since February
I came across this thread while I was googling about the ATR 100

I have just recently purchased one of these rifles in .308 calibre to replace my 1906 Carl Gustav Swedish Mauser which needed a new barrel. Oddly enough I used to own a Charter Arms Field King in .243 now the ATR 100 has exactly the same features as the charter arms rifles and the design had been purchased from them by Mossberg and it became the ATR 100 you guys are talking about. My view on the rifle is it is a great rifle in the budget range and I have found the accuracy to be great, my .308 is equipped with a Bushnell Banner dusk and dawn scope, last night I took it hunting and claimed a nice hog at 150 yards with it from the back of a pick-up truck I used 140GR Barnaul ammo (cheap and nasty zinc plated steel cases) Barnaul ammo is by far not the greatest ammo and has caused me headaches with feeding from the magazine remington 150Gr I have cycled four rounds both fast and slow with no issues BUT I have found that the magazine does not give me issues with the crap Barnaul ammo if I only load three rounds at a time into the magazine. Now this IS a common fault which has stemmed back from the days it was known as the feild king by Charter Arms I had the same problem with my .243(which I used to claim big hogs with) and I did the same thing with the three rounds in the mag and it was fine so it is an old issue that probably wont go away with a fully loaded mag.
As alot of you have said recoil wise it is brilliant(and I am not very tolerant of hevy recoil due to shoulder injury from the past I won't even fire an old .303 and I used to love this calibre when I was younger) I would say the recoil pad is better than the expensive limbsaver pads and I noticed that is has bugger all muzzle lift/climb
Accuracy is great like I said my ATR 100 claimed its first hog last night at 150 yards and I usually miss at that range.
Following moving targets is great due to the short length of barrel and lightness of rifle. Trigger wise the trigger in my rifle does not have much creep and not much effort in the trigger pull
If I were working in a gunshop I would recommend this rifle to anyone looking for an affordable rifle and not wanting to pay rediculous amounts of cash.

Welcome to G&G...

...and, we're looking forward to your range report.

[txdude321]

after shooting my gun for a few range trips now I have come to the conclusion that it is a very nice rifle. at 100 yards i got a 3 shoot group in the center of the bulls eye that can be covered up by a quarter , i am by no means a good shot at all and i wasnt even using a shooting rest just a rock mount bipod and 150 grain federal ammunition

i will try and dial it in even more, so far i am very happy

[txdude321]

yea my mossberg has the adjustable trigger it is very nice

[tommy]

[tommy]
