Went to the range this weekend. There was a fellow next to me with what looked to be a new DPMS (gun show this weekend also go figure). Every time he went to shoot his rifle the first round would discharge then he would have to spend 10-30 minutes working on it. I am not sure but he was removing the entire upper assembly. I think the rifle was failing to extract the fired case. Now I have a RRA (got it before I found M4C) and was very pleased because every time I pulled the trigger it went boom. I kinda felt sorry for the guy. I wanted to let him know about this great forum but he packed up and left (frustrated) before I got the chance to talk to him…I know you guys bash the RRA’s a lot but it will keep me shooting until I can build one with the information I am learning here, and if it keep going boom I’ll keep pulling the trigger.
Thanks to everybody for all of the great information.
my rra did me well too but found the forum, sold it and went custom sbr route…there are plenty of dpms that go bang every time just like the bushies too.
the flavors are well documented on this site & don’t go thinking you will getting high 5’s on your rra praise for a primary defense gun. I do like their stainless varmint bbl’s as every one has been great on paper.
There are some stickies on how to improve what you already got, but if that rra is your shtf gun & you have the coin, just join the disease and get a colt, bcm, dd, etc that has a better track record in the torture dept.
Don’t sweat your RRA. As long as it works for you.
Though I would consider thinking about upgrades or possibly flipping it and buying something better, depending on what you want, and how much either way would cost.
It’s better to have a lower quality gun that you actually shoot, rather than a higher quality gun that you don’t, in my eyes. And as long as it runs, who cares what you do with it.
Just a thought, but you said he was taking apart the whole upper assembly. and by that, i take it you mean the BCG.
Also you said this time was right after a gun show, so maybe it was a brand new weapon possibly?
I would suggest (and i wasnt there to see his body language) maybe he was breaking it in. mopping the bore after every round for the first 10-20 rounds or so. i know my DPMS break in process is for the first 10 rounds, clean bore after every fired round. then go to 5 round increments, then 10 round increments. I think it is going to take me about 160 rounds til its fully broken in. but considering whether he was cursing, or just seeming like he wasnt absolutely having a blast, maybe he was just trying to get those first rounds down range so he can get it out of the way.
Maybe so, but it’s plainly stated in the owner’s manual to clean it after every round for the first 25 rounds and then every 10 rounds up to 100 rounds. He was probably just following the instructions.
He was clearly having problems. He would remove the upper reciever, bcg and charging handle. Then it looked like he was trying to remove a stuck case, after a few minutes of this he would leave the firing line and go into the shop for several minutes leaving the lower and other part there with his buddy. Once he returned the whole process would repeat.
Thanks for the encouraging word 120mm. I’m not sweating it, can’t help that I didn’t know what I didn’t know at the time. Now that I’m a more informed consumer when I have the chance I will add a BCM rifle to my collection. I will keep the RRA as I have a son that enjoys shooting with me. This way we can both shoot at the same time and I don’t have to wait for him to finish so I can take my turn (waiting sucks).
Wish you would’ve checked out one of his shell cases he left behind. In addition to a craptacular rifle, I’ll bet he combined it with the suck multiplier of Wolf/Bear/Tula for good measure. :rolleyes:
Quote: “To achieve the best results for accuracy you should clean the chamber and bore after every
round for the first 25 rounds and then every 10 rounds up to 100 rounds. It usually takes
about 200 rounds per barrel for optimum accuracy. Please keep in mind that our barrels are
production barrels not custom barrels. Accuracy is dependent upon many factors such as
bullet weight, powder load, rifling twist, rifling lands, operator technique, etc. Our production
barrels have achieved anywhere from 1/8” to 1 1/2” M.O.A. Obviously, we would hope
that every production barrel would shoot 1/8” M.O.A., but with all of the above factors, we
cannot guarantee a specific group size.”
Does this mean I have ruined my DDXV? (due to not following the above )
wow. …
all i was saying is the manner you described fit the bill. 1 shot, break down. fiddle with the barrel/upper for a min. build, fire, repeat.
as far as the barrel break in, i dont see how that matters in this conversation. but to humor the post, i will be breaking in my DPMS LRT SASS here in the next few weeks. ill be using federal gold match ammo. ill be using 160 rounds. all things i think are necessary for best results. ive done enough reading to understand there are plenty of great shooters and gun smiths on the forums to start a war on this topic. its more about personal opinion. you may think it is a waste of time, while a close relative with 30 years of gun smithing may think i need to do it. or vise versa. so who should i listen to? im going with the general consensus that it needs to be done. atleast i cant go wrong if it actually does not need breaking in. the rounds are going to go down the barrel either way. the only difference is a quick run with a mop to remove fouling.
1/8" MOA… THAT’s a hoot! All the rounds inside a hole that’s smaller in diameter than a .40 caliber bullet.
Evenodds, when somebody like IG tells you something like that, you can take it as a fact. He knows what he’s talking about, and he has the experience to back it up.
You WILL run into gunsmiths who will tell you to break your barrels in. They may be 100% right - when it comes to benchrest or other precision barrels… but not about the chrome-lined AR barrel.
while I don’t beleive in barrel break in except maybe under very limted circumstances with precision long range rifles, some “break in” as far as smoothing out parts and eliminating rough edges/getting the gun to settle in is often required on production rifles.
The reason some ar’s are cheaper than others is the amount of attention to detail spent on them- the cleaning up of machining marks and such that at least should be done on higher priced rifles that will result in them running better right out of the box compared to low end rifles.
I would not be the least bit surprised if the gun was bone dry or inadequately lubricated and he may have been trying to feed it ammo it just didn’t like (lots of guns run fine with wolf or reloads while others will not tolerate them)
FYI I have a dpms upper on one of my rifles and have never had issues at all,but lubricate well and use quality factory or carefully assembled reload ammo.
That poor guy. I feel his pain. My first AR was DPMS and I cursed that thing to no end when I would go shoot it. Hopefully he’ll see the light at the end of the tunnel.
Not sure why you felt the need to put a grimacing emoticon under a question that was asked in a decent manner. Especially considering that you are coming across as an ass to a guy that has shot bad guys in the face. F2S has earned the right to ask such questions.
