I think its just as mentioned. Lube and bad ammo is probably the root of the problem. I have a lmt/spikes now but wouldn't hesitate owning a double star again especially for a range toy. Did I say that already lol.

Or, on the oppsite side of the coin, the GS reloads could have had the sizing die set too deeply, pushing the shoulder down too far, allowing them to seat too deeply into the chamber, and the firing pin would'nt be able to hit the primer hard enough..One could check these loads with a case gage and it'll tell you right away. Had this very thing happen to me a long time ago..Bought a case gage and set my sizing die up with it, no more problems..
One of the more common reasons for a light primer strike is an incorrectly installed hammer spring. It is possible to put it in up-side-down and have it function intermittently, but there is inadequate spring pressure for reliable ignition. Check to see that the hammer spring is installed like the one in the photo. Note that the legs on the spring come from underneath and ride on top of the trigger pin.Quote:
I chambered a round in his DoubleStar and pulled the trigger - "click". Checked the primer on that round and it was barely dented; tried a few more with the same result. This was using his gun show reload ammo. I tried a few of his gun show reloads in my BCM and they fired with no problem.

Eric's theory is very possible. THis, plus hard primers, hence, he was able to shoot the factory ammo. Was the trigger pull light when you fired it?
BTW... You are a brave man.Quote:

I've got a Doublestar STAR-15 that's more of a mutt now, but it has performed flawlessly for me over the course of about 8 years through all of its variations. As others have said, it will run through any kind of ammo I feed it without a hiccup. I would say the cheap ammo might be the culprit.
Used a Doublestar pencil barrel (from Brownell's) to replace the stock barrel on an M4gery about a year ago. Headspace came in fine, and such shooting as I have done with it suggests that it is more accurate that the barrel I took off ever was.
As for gunshot ammo--I wouldn't take it for free. Saw a Smith M36 blow up once with "mystery ammo". That was on an indoor range, and we never found all the pieces of the gun.
As others have stated it could be a few things, lube, hammer spring upside down, ammo, etc... I wouldnt be suprised if it was a combination of lack of lube, and ammo. I currently own a Doublestar M4 with a heavy barrel, it has performed flawlessly as did my previous 20" A3 (wish I had never sold that one). I have read numerous replys to Doublestar threads bashing them for no apparent reason, usually by people who have never even touched a DS rifle, which I never understood. My DS is properly staked, runs any ammo, is very accurate, and with the $300 or so I saved allowed me to get a Aimpoint PRO optic, whats not to like (rant over) :thank_you2:
Some Doublestar porn for the heck of it
