TWS Dogleg issues/questions
I just finished installing my new TWS dogleg topcover and peep sight on my Arsenal SLR-107F and noticed a couple of potential issues/questions:
1. I noticed that the button on the back of the recoil spring guide doesn't stick outside of the topcover like the stock button does with the stock dust cover. It's not even flush with the cover, it's actually inside of it. Why is this?
2. What is the purpose of the metal bracket that is attached to the recoil spring guide assembly, just in front of the button? Is it to stop the bolt carrier from hitting the rear trunion?
3. When I shoulder the rifle and aim through the iron sights, it seems like the rear sight is not lined up with the front and I have to rotate the rifle counter-clockwise slightly to get the sights to line up. Not sure if it's me or the rifle, but I didn't notice this with the standard sights. How do I check to make sure everything is aligned properly?
4. I have an Ultimak on this same rifle and an Aimpoint T1 on an ARMS 31 mount. When I attach the ARMS to the Ultimak, it is extremely tight and I can't get it off without using a tool to open the lever on the sight. But when I attach it to the TWS rail, it connects firmly but I can still remove it by hand; the way I imagine a "quick detach" mount should be. Why is this?
1. As long as it holds the cover down firmly I would shoot it and see if it moved back a bit. It will wear a bit as you shoot it and should be fine
2. The metal spacer is used on the .308 Siaga rifles and was added to all of the recoil spring assemblies at one time. Look at the end of the big Dog Leg thread here to see more discussion on it.
3. It could be you or it could be that the receiver is twisted a bit. You wouldn’t notice it with the original sights as they are attached to the barrel. Shoot it and see where it hits.
4. With an ARMS mount a slight difference in rail dimensions can make a big difference in how the mount clamps. You can't adjust the mount tension like you can on a Larue or many others, so be thankful it fits both of them.
