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?

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.

before this i only ever shot my pistols and for that a 25yd indoor range was perfectly fine, now that i am getting in to rifles i may actually splurge and join one of the outdoor private clubs.

i was just told today by one of the people i go to church with that there is an outdoor range about 40 miles from me thats is suppose to have a very nice facility, and has several different membership options. the kicker is the initial "Donation" its $100 donation to their land fund then its either $55 working membership or $90 for a non working membership. from there they had several other options for people who really wanted to have a say in what goes on but they were like $300.00 per year.

i am thinking about going out there an checking it out.

25, 50, 100, and either a 200 or 300 yard range.....FREE

not that i am aware of i live in a pretty decent size town just ouside of OKC not a whole lot of places to go shoot outdoor without joining one of the private clubs, the closest place to where i live is the oklahoma city gun club. which i believe are a little steep especially as you must provide your own stands and targets

okcgunclub website said:
Membership dues the first year are $230 - $180 annual dues and $50 initiation fee. The first two years you are a member, you are an Associate Working Member. This means that the first two years of membership you are required to spend one day per year providing some type of work for the club. This can be anything from helping with a match on one of the ranges to cutting brush and mowing. The club has several scheduled work days during the year and the various Divisions schedule workdays for just their range. You are responsible for making arrangements and completing your workday obligation.

this is a little more than i am wanting to spend for the maybe 15 times per year that i would shoot

maybe after i get set up on reloading i could afford to do more shooting and it would worth it.

Not sure if its an option there, but check with your local police or any FOP member. They use a range somewhere, and could be a cheap option. Even if you are not law enforcement, they offer what is called an "associate membership" (you just have to be sponsered by an "active member"). My Lodge here has a 50 lane range and my dues are $62 a year.

Have you gotten this fixed yet ?
Sitting here at work (midnights) and going thru the older threads.

nope not yet, still havent forked over the money to the OKC gun club and the other is just two far away, i know i would rarely drive all the way out there so for now its either get in good with a guy from the okc gun club or continue to shoot indoors.

Talking about the bolt hold open problem at the beginning of the thread

G

Discussion Starter · #18 · Oct 27, 2007

yeah i think i have it narrowed down to weak ammo or my weak as grip on the rifle. i changed ammo and still had a little bit of a problem but it seemed to disappear once i put the stock tight against my shoulder,

also no problems what so ever with 5.56 ammo either way but i got a much bigger flash which i could see as a potential problem shooting in low light conditions.

i have a G19c that is my CCW that i carry during the colder months that i had to get a standard G19 barrel for because it messed with my vision. i am told its caused by a bad astigmatism

im getting custom lasiks in january that should correct my astigmatism and hopefully fix that problem

ETA: ammo types used thus far in order of usage

.223 Aguilla 55gr
.223 HSM .55gr
Priv Par 5.56

Its the mags. Try a Pmag or a new spring with a Magpul follower.

I'm wondering if part of the issue might be a bad spring on the Bolt Hold Open lever..
