Hi all, I have a DTI-15 from Del ton Inc, and am having some major troubles with it. When I first tried to take it out to shoot, it would not even strip the first round off the magazine and send it to the chamber all the way. It would end up half way in, or almost in but the bolt would not seat properly, with no effect from the forward assist. So I was thinking maybe a weak buffer spring at this point. But before I made any mods to it I took it to a local (northwest florida) gunsmith, who proceeded to cycle a whole magazine worth with the charging handle. His advice was basically to "not be gentle with it". This made sense as it is a mil spec rifle. I then took it home and cycled another magazines worth of rounds through it. Ok so fast forward to my next range visit. The first round enters the chamber fine, and I would then get a max of probably 5 rounds through the gun before a jam. The majority of jams are the round just not entering the chamber fully. Once I ejected the stuck round, I found them to be bent and scratched up, with the bullet actually able to be removed from the casing on a few of them. Ok so my next thought is bad magazine. I then proceeded to borrow two mags from another shooter at the range, 1 armalite 10 rounder, and a 30 rounder that I'm not sure what the brand was. The person who lent them to me said the 30 rounder had a special follower on it so it should be real effective. The armalite ran about 3 mags through before a hangup, and his other mag was about 50 percent effective. So I am kind of at a lost with all this. Now keep in mind I have not changed anything yet. I may switch buffer springs for the next trip to see. But with 4 different magazines (PMAG, Armalite, a generic 30 rounder, and the mag with the special follower) I am not getting anything consistent from the gun. The rounds are PMC bronze fyi. I am going to run it by the gunsmith again but in the mean time, what do you all think. At this point my best guess is maybe a bad feed ramp, but this problem may be getting over my head. So any help is greatly appreciated. Thanks in advance and take care. Bobby Wanna kill these ads? We can help!
