Re: Idea! Official DTA SRS, HTI, Covert, Hunter Th
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: mhines</div><div class="ubbcode-body">I just got a DTS SRS, I was going everything on the gun and noticed when I change barrels following the procedure.
1. Remove buttpad and bolt (see page 15)
2. Using a 5mm allen wrench loosen
the four barrel locking screws (fig. 3a)
3. Using a 5mm allen wrench rotate the barrel lock counter clockwise 180˚ to unlock (fig. 3b)
4. Pull out barrel.
Then doing the barrel replacement
1.Insert barrel into the receiver, note the locating notch on the barrel extension
2. Fully seat the barrel against feed ramp.
3. Ensure the caliber of the bolt matches the caliber of the barrel (fig. 6)
4. Insert the bolt mechanism into the receiver (fig. 7), fully close the bolt engaging the locking lugs in the barrel extension; this establishes headspace.
5. Using a 5mm allen wrench tighten the four barrel locking screws to 68 inch / lbs of pressure
6. Using a 5mm allen wrench rotate the barrel lock clockwise 180˚ to lock.
I noticed that the lock will continue to rotate past the 180'.
I just wanted to make sure that is normal.
Also I was just curious what is the lock/unlock actually doing?
Thanks </div></div>
Mine did the full 360 degree rotation.
If you look down the inside of the chassis without the barrel in there, you'll see a little plate on the bottom that adjusts up to loosely hold the barrel in while your tightening the actual barrel screws.
