Hi, just experienced a missfire on my DTS. inspection of the primer showed a light strike, previous two rounds also appeared to have been lighter strikes, but those rounds fired. Stripped the bolts and everything appears to be ok, nothing broken, no dirt or debris. Only anomally was that the endcap spring seat appears to be slightly rounded, such that the spring does not sit square on the seat so the cap can "rock" on the spring. When reassembling the unit and cocking decocking the bolt the mechanism appeared to "bind". Gave the bolt a tap on the bench and the binding stopped. Could not work out if the binding was the end cap in the Sleeve or the Striker in the Sleeve or Bolt body. Has anyone had any similar problems or ideas? Rgds Phil

I have not experienced this problem, but first a few elaborating questions:
  • Gen 1, A1, or A2?
  • How many rounds have you shot with this bolt?
  • Reload ammo? If so, what primers do you use and how do you seat your primers?
  • Have you contacted DT warranty?

In my experience, DT will do warranty work long after the factory warranty has expired.

Hi '91, Rifle was bought second habd, serial No starts with SRS so believe it be to an early model, Think that there were only 450 rounds before I got hold of it an I've put 140 through it, Ammo being used was manufacturers Norma. Never had a problem with this ammunition and I've used it for a number of years with other rifle. Problem just happened today so in process of contacting DT, but had an early query about Bolt sleeve moving forward and preventing cocking of bolt if I was too energetic when cycling bolt. DT were not vey helpful, but how they could ignore such a problem on a firearm which they promote as being good for Tactical use by military or civilian enforcement purposes is beyond me, still have the problem on occassion just live with it now, but will try them and see if I get a response.

Cheers,

Phil

Something sounds off. Could you record a video cycling the action?

Take pictures too. I'm curious if the bolt is assembled correctly.

Hi Whiskey91lima, sorry for the delay in responding. Work unfortunately interferred with play and been checking manuals and Bolt, but had also posted a query on Primal Rights who asked a telling question about the cycling problem I was having.

However to respond to your query about the Bolt assembly, thankfully I had assembled it correctly, as per manual which is not all that good, but configuration corresponds to photo's in manual. Please see photos of my Bolt. Am at a loss as to why it appeared to be sticking on reassembly, but now appears to be free enough. As for misfires/light strikes as everything was clean It may well be operator error in not rotating bolt fully. Will try again with a bit more care when I can get to the range.

As for the cycling problem I mentioned, Orkan from PR mentioned a sleeve stop screw. Inspection has revealed that there was a plastic screw fitted which was flush with the receiver bolt channel so it was not stopping anything, this allowed the sleeve to move forward, on occasion, and prevent the bolt from turning as the bolt endcap detent pin did not clear the long axial slot in the sleeve. All I have to do now is to try to source a sleeve stop screw.

Thanks for your assistance, regards Phil

That looks like an older bolt design than the bolt in my A1. I'll take some pictures of mine for you tonight.

Hi, Wiskey91Lima, Yes your bolt is the Gen 2 I believe. In discussion with DT, the light strikes I've experienced may be a function of its age and usage. Which tends to raise the question about how many rounds have gone through it. Unfortunately there was no log book with it, just hearsay. Trying to decide weather to upgrade to the G2 bolt or fit a new spring.

thanks again for your help,
Phil

If you can get new parts, I'd do that. Though I do wonder if the Gen 2 is designed to have a longer lifetime or not.
