I have an ATec mod for the end of my Sako 75 in 308. The mod sits very well when first screwed on but after a bit of carrying in its slip or a few rounds down the barrel, it almost always works loose. Is there a product like loctite that I can use to tighten the thread up a touch? It sounds precious but the rifle is a deluxe model that I've done quite a bit of hidden accurising work to and is therefore quite difficult to replace so I'm very wary (read paranoid!) about corrosion, etc. Any suggestions very welcome!
I'm out on the hinds on Thursday and Friday and won't have a chance to re zero - what do we think? Same point of impact if I am able to increase the friction in the thread or will the mod have moved?
