Mil-spec and commercial receiver extensions/buffer tubes share the same thread pattern. They're interchangeable as far as screwing into the lower, just unique when it comes to stock fitment due to the difference in O.D. Score. I have the Gen 1 Recon, and a spare Milspec tube with Vltor EMod just waiting for me at home. I was so sure they were different that I never tried them. |

The Gen2 utilizes a standard length AR15 receiver extension. I'm not sure if the receiver extension for the Gen1 LR308 is longer or not. You can make it work, but it will all depend on the stock tube length, buffer weight/length, and spring combination that is used with the Gen1. |

The DPMS gen 1 also uses a standard length buffer tube with shortened buffer.

Yep, the threads on a Mil-spec extension are forged onto the tube where the commercial threads are cut out of the tube. If you look at a mil-spec one you can see the threads are taller than the tube. |

Looks like the takedown pin is standard AR15, the pivot pin is unique to the G2 http://www.ar15.com/forums/t_2_627/247573_GII_Cross_Compatibility_Chart.html Receiver extension is standard AR15, but the buffer and spring are uniques to the G2 I can probably get you the od of the ejection port cover pin, but the length can not be obtained without disassembly Quote HistoryQuoted:

Op and mn hunter have convinced me to start selling some of my armalites. Im going to ty an AP4 out but ill lighten the barrel a wee bit, put adj gas block on it and the MI HG. The combination of the weight and the narrow diameter handguard sells it. Ill probablyb skeletanize the mag well and bolt carrier too just to take it to the limit. I am goint to try to take this build to the limit. Can someone please mic the OD and length of ejecton port cover pin? I am going to try try and get an aluminum pin. Also, does this thing use a standard AR15 receiver and buffers? Does is the rear take down pin a standard AR15? What about the front? Thx Looks like the takedown pin is standard AR15, the pivot pin is unique to the G2 http://www.ar15.com/forums/t_2_627/247573_GII_Cross_Compatibility_Chart.html Receiver extension is standard AR15, but the buffer and spring are uniques to the G2 I can probably get you the od of the ejection port cover pin, but the length can not be obtained without disassembly I would really appreciate it if someone could mic it. Honesly, I might just leave it off, that and the F/A. But plase give me a minimum lengh of the pin that I shoudl order so I can shorten it as needed. I posted in DPMS G2 forum questions about the length of buffers with different reciever extentions. I suspect that the Vltor long car reciever ext will work with a standard AR15 carbine buffer... we will see. I can save weight by replacing the takedown pin, castlenut, endplate, selector, grip screw, removi g the f/a, replacing port door pin or dumping the assembly alltogher and skeletonizing the carrirer and mag well and taking a we bit off the barrel.. get below 6 easy if i use the ctr butt... Any other ideas? |

bros,
can someone please measure the buffer length. DPMS is not responding in their forum. Just let us know whether the gun has a rifle or car stock as well. Thx |

Thx G2 buffer from stock AP4 with carbine receiver extension measures 2.5 Slash's CAR-10 buffer measures 2.605 for comparison Ejection port cover pin measures .123 o.d. Inside span is 3.53, so you'd probably be somewhere around 4+ in length |

I am however concerned about recoil with a 308 in that light weight. Have you found the recoil and muzzle rise to be manageable. Edited to remove the question asking if op was pleased with accuracy. I missed the statement of the obvious

yeah, 308 recoil is not worth mentioning. not like im some sort of crosssfit manimal or anything. mussle rise recoil? nobig deal, all it is is hwrder to do twctical followup shots.

Quote HistoryYep, the threads on a Mil-spec extension are forged onto the tube where the commercial threads are cut out of the tube.

No sir. The Milspec tube is made from an impact extrusion. The threads are machined after extrusion. what does impact extrusion mean? i know what extrusion is generally. how exactly are the threads made on milspec tubes? all i know is that they are not cut like when you thread a pipe like commercial extrusions are. on milspec extrusions you can actually see the peaks of the threads are taller than the surface of the tube. |

I agree. what part of fl you in? jax i must have been drunk on my phone with that post. what i meant is that 308 is harder to do follow through, to spot your own impacts at range, and it is harder to rapidly concentrate a high volume of fire on target. now since in manuver gun battles, most rounds are expended as suppressive fire, a system that allows you to carry more ammo and shoot faster from awkward positions is better. but for certain circumstances, like close up roshambo type exchanges of gunfire that dont involve magazine changes, 308 probably makes more sense, particularly if it is braked. but the recoil is not harsh unleass maybe you are shooting 175+ ammo from a mountain gin or something., its at the bottom rung of a hipo cartridge. |
