Newbie Question on DPMS G2 Hunter .308


TexMex1959

Recommended Posts

Hello, Newbie here.

I've had my G2 Hunter for a few months.  Shoots great, loves P-Mags, not one FTF.  My question is this.  Is the BCG supposed to stay open when the last round is fired like my AR-15s? Mine stays closed after the last round has been fired.  I asked a buddy who builds AR-15s and he told me that this particular gun is built this way.  Seems odd to me.  I hope that my first post is not a stupid question.  Thanks in advance.

What ammo are you feeding it and how many rounds have gone down the pipe?  I think the round count is a good question. The other suggestions will be good, but break it in a bit and see where it goes.  Stick with some heavier bullets (unless that's what you're already shooting), then go to the bolt catch or different mags. Sounds like the other thread the pmag wasn't allowing the the catch to go high enough to stop the bolt. Should be something similar with yours I would imagine.

Thank you all for the replies. I am running factory Federal 168 Match  ammunition.  

I will try the factory DPMS mag and see if it help. 

 I cannot manually hold the bolt open. The round count is about 90 at this juncture. 

I'd rather not send it to DPMS as I have replaced the trigger and changed the ambi safety to a single lever. The ambi safety bothered my trigger hand. 

Thank you all.

  So your saying , when you hold in the Bolt Catch , with the BCG all the way to the rear , the Bolt Catch will not engage the Bolt face & hold it open ?   Or with an empty Mag ( of any Brand ) & you pull the BCG back all the way , it also will not engage the Bolt face & hold the BCG back or open ?

  I keep hearing some people say that you have to break in a factory 308AR for it to function properly , why would you need to do that I ask , does anyone need to do that with other Firearms, right out of the box  ?

   Now to have a sufficient round count for a duty or firearm used in any kind of combat or work related use , where your life or others lives may depend on said firearm , yes, I would want to make sure it had sufficient round count that I could depend on it , but thats a whole different matter . Its not that its not working , your just getting piece of mind . Its not like a good buck may get away because your firearm malfunctioned or the paper target got away because the firearm didn't work , if you get my meaning .

 A home build is a different matter all together . I sold Firearms for over twenty years & never had a factory Firearm brought back because it malfunctioned or wouldn't work , not one , maybe I was lucky , but thats a lot of luck , we are not just talking about class one firearms , we are talking about class three also.

  Your G2 should work right out of the box , period , if it doesn't , send it back , thats why it has a warranty on it by the manufacturer. They could have a machining process that was not complete or a worn tool out of spec's & they got a run of them & of course they will not say anything , to have two in a sort time span , I'll bet there are more .

  Put you original components back in & send it back , if you have them still . They can effect BCG movement . Thats another question , did it act this way before you changed them out ?

 

  Also , I only have one AR with a Ambi. Safety & it gets in my way a little too , but its for my lefty wife anyway.

You are correct SS. A factory gun SHOULD work straight out of the box. 

 

You mention you've changed the trigger, is everything else stock?  If so you're probably going to focus on the bolt catch. Either it is out of spec, or the mag you are using will not push the catch up far enough and may require some fitting as the OP did in the other thread. If you pull the bolt back and manually set the bolt catch, that functions,right?

Update:

 

tried the DPMS factory mags and the bolt will stay open after the last round is fired. 

Honestly, I liked the P-Mags so I just went and bought a few and never tried the DPMS mags. 

Looks like I have my answer. I have a 10 and 20 round DPMS mag and will probably get more unless y'all recommend the Lancer mags. 

Thank you for helping me!

Why is it with the G2 that a Pmag won't work? My LR-308 has no issues with them at all. TexMex if you're looking for a home for those Pmags let me know.

because magpul redesigned the pmag to the gen3. the gen3 follower doesn't reach or sits lower than the previous pmag and it doesn't engage the bolt catcher all the way. i have the same problem. luckly i found a local gun shop that still carries the old pmag with the black follower. the older design works flawlessly with the g2
