ok i'm building my first AR and am just starting out, (I only have the Lower Stripped Receiver From Essential Arms)
here is what i'm looking at getting before the questions begin: 16in barrel chambered in 5.56 nato, quad rail forearm rail topped upper reciever, piston opperated. i'm trying to get an M4 type of thing going on. I'm still Deciding what I want but have a few questions to help to influence my decision. 1. Are all .223 Cal barrels capable of firing the 5.56 Nato round or is it the other way around? I haven't seen too many barrels chambered in 5.56 which makes me wonder if this even matters. 2. Piston operated. I have been seeing that there are issues with fitting a quad rail setup with a piston block. Also are there any piston blocks (i don't know about the terminology on that) with rails on them for mounting third party front sights and whatever else. 3. is there a site or some type of list that shows the differences between the different types of m4's as in A1, A2 if there is one??? 4. Are there any issues with the piston opperated blocks and a .22 conversion kit? 5. If i seem like i don't konw anything about this, that's because i really don't, please help... |

I haven't seen too many barrels chambered in 5.56 which makes me wonder if this even matters. .223 is ok in a 5.56 but not the other way around 2. Piston operated. I have been seeing that there are issues with fitting a quad rail setup with a piston block. Also are there any piston blocks (i don't know about the terminology on that) with rails on them for mounting third party front sights and whatever else. Can't help much with pistons, someone will be along shortly 3. is there a site or some type of list that shows the differences between the different types of m4's as in A1, A2 if there is one??? This site will have more than enough info. If you are looking for pics, there are several tacked threads at the top of the forum 4. Are there any issues with the piston opperated blocks and a .22 conversion kit? My understanding is that a .22 will not operate the piston, rendering the the rifle a single shot. May be fix but I'm not qualified to discuss pistons - someone will be along shortly 5. If i seem like i don't konw anything about this, that's because i really don't, please help... Read......A LOT. There is a wealth of info on this forum. Have fun with the build |

I haven't seen too many barrels chambered in 5.56 which makes me wonder if this even matters. NATO handles all, plus there are other chamberings like Wylde and Mod 0 that shoot both types of ammo safely. They were designed to handle NATO spec ammo more accurately for competition. 2. Piston operated. I have been seeing that there are issues with fitting a quad rail setup with a piston block. Also are there any piston blocks (i don't know about the terminology on that) with rails on them for mounting third party front sights and whatever else. The piston blocks I have seen are taller so you would need to use a front sight for a railed forearm not gas blocks. MBUS might not be great for this because of the heat. 3. is there a site or some type of list that shows the differences between the different types of m4's as in A1, A2 if there is one??? 4. Are there any issues with the piston opperated blocks and a .22 conversion kit? .22 conversions are blowback operated so I don't think it would matter if it is a piston upper or DI. 5. If i seem like i don't konw anything about this, that's because i really don't, please help... I personally wouldn't bother with a piston rifle. They are heavier, less accurate, and harder to find replacement parts for. The only benefit is when shooting for long periods without cleaning, you don't need to give it a shot of oil every 4-500 rounds. That isn't worth it to me. |

As I understand it, the only variation in M4's is one being auto and the other being 3 round burst. I suppose neither of those will have any effect on your build.
The Adams arms piston kit has a gas block with a rail so you can attach whatever front sight you like. I'm sure others do too. As far as .22 lr running a piston operated gun, I'm not first hand familiar with conversion kits or piston guns, but I'm pretty sure the .22 kits are blowback operated, meaning they do not need a gas system at all. Only question will be if the kit will fit when the piston is installed, or if you can remove the piston. |

Seriously, it's a bit naive to assume that piston-AR's will automatically be less accurate than their DI counterparts. The accuracy of any rifle is attained by many factors. The quality of components used in the build being one obviously. Take a DI-AR, and build it with bad-ass parts, such as BCM, DD, etc. I'll venture to say it will be more accurate(on average) than a plain-jane DPMS off the shelf. Why is this? A piston could be less accurate or more accurate depending on many things: barrel, carrier, bolt, handguard, gas block, sights, trigger's, upper & lower receiver, etc. See my point? Because it's the sum of the parts that make an accurate rifle. Many have posted pics showing just how accurate these piston-AR's can actually be. IMHO- If you are building your first(and only AR15 so far), I'd stick with a DI. |

I mean couldn't one say after shooting a piston gun why the heck did i consider a DI gun? |
