I just got a new FN SPR. The trigger is an old style model 70 type set at 6#. When I took the action out of the stock to adjust the trigger to 3# I found that FN had epoxied the nuts on the trigger so it could not be adjusted. I don't know why FN would make an adjustable trigger and then make it so it can't be adjusted. Does anyone know how to remove this epoxy. Also, is there a BEST way to break in a chrome lined barrel.
Thanks

Shoot it.

Chrome barrels do not require any special treatment for break in. As JHS stated, go and shoot it. As to the trigger, I think Acetone will disolve the epoxy but be careful to get on the epoxy only.

Thanks for the replies I never did like going through the break in process. Acetone doesn't touch this epoxy, it's as hard as a rock, more like JB weld.

Have you tried a heat gun?

I heard FN had epoxied the triggers, but mine was not epoxied. I think mine was 3.5# when I got it and I dropped it down to 3# (as low as it can safely go on my rifle).

Heat gun is an excellent idea. Mini torch as well but be sure you know what you are doing.

The heat gun works! It took the heat gun 4 to 5 seconds to melt the epoxy so it could be pushed off. Excellent idea. Thanks.

I did a timney on my a5m - problem solved

Where do I find the torque spec for the action fasteners?

I was told by the people I bought my rifle from that they torque the guard screws to 65 inch pounds, but I talked to someone a McMillian and they suggested that you start at 30 inch pounds and do a ladder test to see which works best.
