went and shot my DPMS for the first time today got it sighed in and was shooing half inch groups from 25 yards using the iron sights and hitting center mass couldnt be more happy with its accuracy, my question is this

upon shooting the final round shouldn't my bolt lock back. shot around 75 rounds 5 rounds at at time (sorry was trying to prolong my enjoyment) and not one single time did the bolt lock open for reloading. however as soon as i pulled back on the charging handle it would lock in place. what could be the problem or is this normal.

its not really a big deal to have to lock the bolt manually but id prefer it to function as it was designed,

thanks in advance for your comments.

definatly not supposesd to function like that. try different mags sounds like a weak spring maybe

Your bolt should lock back after firing the last round. Here's a few questions that might help isolate the problem.

What type of magazines are you using?

Did the problem occur on the same magazine? Or did you try different magazines with the same results?

Get some Pmags or NHMTG.

tried two different mags from different MFG both have the Green anti jam followers.

one says its Sanchez (dSl the other was New Brittian

had the same problem with both the NB was just purchased new Friday from a surplus store.

exactly what springs are you thinking might be weak.

try different ammo and new mags. if the gun is new and the buffer spring is ultra strong then it might be short strokeing the bolt. enough to load but not enough to get past the bolt catch.

Open that distance up to 500 yards you should be able to shoot minute of bad guy at that distance

range only goes out to 25yars or i would have tried for a longer shot, the closest the only out door range near by is a private club and alas i am not a member. not to mention it was quite windy today.

problem = worn mag springs

solution = replace springs

I feel ya. The only range I'm able to shoot at 500 yards on around my area is the Marine Corps Rifle Range. The other range I shoot USPSA at has I think a 300 yard rifle range.
