Just an update on the trigger for my atr 100.The manufacture of the after market trigger finally sent me an e-mail and i quote,[We stop making triggers for Mossberg rifles,because they have several ways of mounting the assembly to the receiver.It got to the point we could not instruct customer which one to purchase.]
Ok with that being said i decided not to take a chance on the aftermarket trigger.
I took a look at my owners manual and sure enough,it shows a travel/sear adj. on the back and a pull weight on the front,just like the one that T.O,Heir had posted.I bought the rifle new at Walmart about 10 yrs. ago.Then why do i not have any adjustments on mine?
Guess the aftermarket guy answered that,MOSSBERG.
Well after looking at my manual,it occur to me i,ve seen this before.Took the stock off my Howa 1500 and there it was,only mounted to the receiver different.Actually took the atr trigger and mounted it on the 1500,no problems,cycled the bolt,fired and safety all worked fine.But you can,t put the 1500 trigger on the atr.
So i did more research and found that you can make it better by putting a bic lighter spring in it,but i went one or 2 better.I took a 4-mile round trip to my local hardware store,bought 2 small set screws with nuts, and a small brass wood insert nut and about 2hrs. later i now have a fully functional,adjustable and safe atr 100 trigger,with a nice crisp,no creep,3-pound pull.
Cost less than $10.
