@Combat_Diver
In your time replacing M4s/16s, did you ever see a lower cracked or damaged or the FCG holes penning? And when you replaced the barrel, did you continue to use the same upper receiver? Thanks. |

Some of our M4's have well over 200,000 rounds down range. Barrels have been replaced, gas tubes have been replaced, BCG's have been replaced but what sets it apart from the AK47's is that upper and lower receivers continue to function. AK's get to about the 100,000+ round count and rails on the receiver will start to crack. It's an easy fix with tig welding but they crack. We have yet to lose an upper or lower receiver from cracking. |

Battle damage due to blast, impact or dropped from helos, yes. No on FCG holes peening. Yes, uppers are reused. There is an inspection criteria that we go by to inspect. CD |

I'm not sure how that could happen though maybe the springs aren't holding the pins? |

Anyone have a small section of military camo netting they don't need? I really don't want to buy a whole 10x20ft net just to use a small section to paint this. It's the only way I can match the paint scheme of the camo abomination (mine) below.

Looking for some clarification on block 1’s. Aside from the standard a2 fh and kac nt4 as listed on page 1, is there a list of “clone correct” or acceptable extended flash hiders? I’ve seen the surefire 3 and 4 prong, and the A2x. Are there any others?

What’s the easiest way to figure out if the SOPMOD stock I have is a gen1? It’s old and been in .mil circulation until a few years ago. I can email pics to someone who can advise.
It’ll be posted in the EE once I verify it’s legit. |

  Still my main go-to. I really want to put an RMR on top of the ACOG for passive under nods, but I couldn't justify it based on how little I've been shooting for the past year due to the ammo situation. Perst3 isn't clone correct, I know. |

The gen 1 B5 contract that I’m aware of was for big Army, not SOF. But at the end of the day shit ain’t that serious IMO. I would run it. |

Was hoping to stay as clone correct/acceptable as possible to block 1, but wanted to use something other than a standard or extended a2. Looking at the charts, if I did use a surefire, but kept my aimpoint in a Wilcox mount—does that still keep me in the block 1, or does that drift into the 1.5? |

Haven't much lately due to it costing the price of a new TV to do a little sport shooting, but the only AR (or any semi-auto rifle) I have is my Block 1/MWS clone. I built mine more to real-world utility using military approved/used components so I know it would work in rough conditions if need be. Just happened to be that was the Block 1 specs, which for me has more or less morphed into the MWS concept which is just an evolved Block 1. |

This is way over due but it is finally complete.
Only a few things that I couldn't or decided not to clone due to money or function. The color is off, but I prefer the color on my clone over what I had available for my service rifle. 1) burst/semi vs semi = money/NFA 2) 14.5 vs 16 barrel = NFA 3) EOtech 551 vs EOtech Exps3 = function My rifle in Afghanistan  Attached FileMy clone  Attached File Attached File |

I am still planning on building my block 1. I'm still torn on what fh I want to use. Traditionally I would use the a2 as that was what was on our m4 when transitioned to the m4, or the nt4 that we used with our kac suppressors. My issue is that I've been contemplating either the surefire sfct as it looks similar to the as but accepts so suppressors. All my other guns have 3 or 4 prongs on it. Either that or just an a2 and not use suppressor.

The only reason I wouldn't is the ability to mount a bayonet. |

Just purchased a new 6921 to replace my chopped psa upper on my block 1 build....it never stops....
For this one, although not clone correct, I’m pinning a surefire Sf3p. The extended a2 never grew on me, and I don’t want to use a spacer for a normal one. |
