Here's my new LR-308... the scope is temporary.  The Bushnell scope I ordered for it is a whole another story.  

First the rifle:
Problem 1.  When I brought the rifle home, I manually cycled a few rounds through just to make sure everything worked.  Well a round became trapped in the chamber with the bolt closed.  I had to hit the butt on the ground a few times before it would release the round.  I have a total of 10 rounds through it now and it now longer "locks" down on a round.  (I think this was just new gun tolerances)

Problem 2:  The manual mentioned that the upper would be "tight".  My is not, it seems unusually loose.

Problem 3:  This is the one that has me concerned... check the picture below.  When I manually cycle a few rounds, they come out looking like this (notice the indention).  Makes me wonder how close I came to this thing firing a round in the house.

The indentations on the primer are normal for an AR type rifle.  ALL ARs DO THIS.

Before chambering or shooting anything you did swab the bore/chamber didnt you?


Not all ammo is created equally and some of it is out of spec.   I've shot some of that NNY marked serbian stuff and it isnt exactly federal gold medal match.

Upper to lower fit is largely irrelevant in AR platform rifles.  Dont worry bout a little wobble.   It really does not matter.


This is your first AR isnt it?



As for an optic, please dont put a bushnell scope on that rifle.....

:)   You can tell huh?     I went from zero to one LR-308, one complete AR15 lower and one stripped lower in about a month!  I guess my AK will get rusty before I pull it out again.


About the scope... I had one of these ...  Scope  but the green reticle would not shut off so I sent it back, now they are on back order.

On that rifle I'd really try to steer you towards a higher end optic.   I started out with a Leupold VX2 4-12x40mm and it's a pretty good starting point.   You could drop it in one of the Armalite 1" mounts ( you can find em cheap ) and you'll have an inexpensive setup that's up to the accuracy potential of your rifle.   Alternately look at a supersniper 10x fixed scope.  


The leupold on my LR before I sprang for the $$$ for a Leupy Mk4


A good optic and an aftermarket trigger make those rifles come to life.  You really wont believe how good they shoot.

Yea, I'm not too excited about the trigger.  Feels like trying to cut a paper clip with a pair of dull scissors.   I still have a way to go before I get her broke in but I can already tell I need a new trigger.

You might try polishing it up a bit.  Mine was fine, but I've experienced some less than satisfactory triggers from DPMS before.  They cleaned up with a little polishing.

The JPEnterprises trigger is a good choice, so is the RRA two stage.  The Geissele might be a good choice, it is the one I'm considering for my DPMS .308 when I get around to it.

Trigger replacement should be every LR-308 owners first upgrade.  JP, CMC, or Timney are all good.

Make sure its got lots of lube when you shoot it.  It helps with break in.  Bolt lugs especially.  Polish the chamber too.

I have a Giessele two stage trigger. The first stage is 2 lbs. The second stage is 14 ounces and can go lower if I like. This is the Cadillac of triggers IMO.
Get some American made ammo for the first 100 rounds in your new rifle. Remington makes some good but not very accurate hunting loads. They will cycle through your rifle safely. Save the R-P brass. Or you can throw a couple of boxes of Black Hills or however much you can afford. Midway has some good sales occasionally through their email list. Get on the list.
This will get your rifle broken in safely. Please don't bang the butt of the rifle on the floor with a live round in the chamber.

Is that rifle a LR-308B?  I'm not positive.  That's the exact rifle I'd like to buy some day.  I hope all your problems with it go away.

you definately need to go shoot it before worrying about the chamber tighness.  DPMS is always happy t oanswer question so call them. Shane is a good contact. always better toy ask for him the to risk getting some new guy.  But for now no big worries with yours.

It's the LR-308T....  I've been working too much lately and I'm 'chomping at the bit' to get this thing broke in!   Looking for a good deal on ammo.....

You won't find any ammo that is more accurate than typical handloads. Save your money on all that factory ammo and start to gather equipment for reloading.

I would recommend not mixing a new, unfamiliar gun with live ammunition in the house in the house.  Especially a semi-auto.
