New AR build recommendation:Midlength or Carbine?
It's been over a year and getting to finish my first AR. Need help selecting an upper.
Got a spikes lower, spikes T2 buffer and lower parts kit. Looking at spikes complete LE uppers in a 16 inch barrel to finish it off. Can't decide between their carbine length or midlength gas system. What would you guys recommend? |

Some say middy some say carbine, I have both and I can't tell the difference, recoil wise. I run h2 buffers and they feel the same to me. The st-2 buffer is very smooth, that being said I have run them in my mid and carbine length 16" and there is no difference to me. Maybe someone will chime in with their thoughts.

You will not feel the impulse difference. I prefer the mid length because of the extended grip surface area

I would add that in addition to the greater grip surface of a middy, you get a slightly longer site radius with it and some would say better functioning because of the longer gas tube.
I'm superficial and just like the look and feel of the middy. |

Carbines with 16" barrels are overgassed and are almost twice as much pressure than a rifle gas.
Mid is closer to the pressure of rifle gas If you shoot thousands upon thousands of rounds, you may have earlier wear on certain parts with a carbine vs mid Best reason to go mid is for real estate |

One advantage of 16 inch carbine length systems is, due to them being over gassed, they do well with the cheap lightly loaded Russian ammo(Tula, Wolf, Brown/Sliver bear).

I tend to shoot heavier 77 grain bullets that cycle the action a bit harder than standard 55 or 62 grain ammo. I run mid length on my 16" uppers, but would prefer the longer intermediate length gas system to smooth them out a little. For the ammo I run, mid length would be better suited to a 14.5" barrel.
I'd only go carbine length on the gas system if I were building a short 10" -12" pistol barreled upper, or something really underpowered like a 300 BLK (pistol length gas would be better for the 300)

You will not notice a difference mid vs carbine. Supposidly the mid will bemore reliable because the dwell time for extraction is more ideal but I have never experienced one way or the other with either. The biggest benifit for the mid is the longer sight radius for iron sights. You can accomplish the same with a free float rail and carbine gas system. So in short, decide which sight system you want to use.

Being we're stuck at 16" barrels mid length.
I started with a carbine but the extra 2" of barrel it really makes the carbine look a bit awkward IMO. Also the mid length system is optimized for 16" barrels being the pressures. Also offers slightly longer sight radius so that doesn't hurt. Won't make or break your rifle I shot about the same with both my carbine/mid length Also the other main reason I switch from carbine to mid is because it offers more real estate to fully extent my support arm and lock out for my shooting position. But as for the "less recoil" I do not feel any noticeable difference shooting my carbine vs middy upper with the same XM193/m855. Neither is a bad option just weight you pros and cons and what you want your rifle for. Initial Build Tacticool Phase Magpul Phase 2nd build (later sold the carbine) Current set up vv Everything I listed besides hand guard area isn't noticeable to be 100% honest. That and the cleaner look. Other than those 2 things the carbine was fine Last edited by CK_32; 07-07-2013 at 7:17 PM.. |

I'm 6'4 with arms the length of a Condor's wingspan. When I move my support arm/hand forward on a carbine length handguard, I run out of handguard. For me, a midlentgh is a little more forgiving. Plus, I personally don't like the look of a carbine. Too much naked barrel for my tastes. YMMV.

Mid for looks. Now that I think about it. I dont even have a mid length rifle.

Guys are all over the PSA uppers. But I've yet to see a full in detail spec sheet and don't fully believe they are the ONE company that found a way to make high end uppers for low end price.. They are cutting costs some where and no one can fully verify where or how or if they are full spec for cheaper. But they run so on a budget it's a decent place to look if your interested in going PSA. But again I won't fully reccomend their uppers being I don't not had anyone been able to fully come out with a hard fact spec sheet and how they are selling "top notch" uppers for less.. way less than every other manufacture today. Being I helped run a business and have been around machining for a while it just doesn't happen like that. So look at BravoCompanyUsa.com when they get uppers in. Or keep an eye on PSA id your on a budget. |

For my first build, I went with a midlength because everything I read online had me believe that it has dramatically less recoil. For my second build, I went with a carbine just to have something different. They're both equal in my experience. The carbine is lighter due to the shorter rail, but it also has less space to place my support hand.

I have both a middy (14.5) and a carbine (16) and the middy seems smoother than the carbine. they also say since most carbine gas systems are over gassed they are more reliable and using low power ammo in a middy may get some cycling issues, never really tested that theory in my middy tho....

Another guess would be less attention to detail in general, like the chamber on the barrel extension may still be sharp as opposed to being properly deburred or had the edges broken properly, or a parts kit was shipped without a pin or spring or something. This again is a quality issue. Also less people answering phones and e mails helps cut down costs too. That being said, I have a PSA upper that I bought during last years black Friday sale, and I have been nothing but happy with it. They make good, not great, stuff, and you do get your moneys worth. I'd say 90% of all people are happy with PSA's actual products, and 90% of all people are unhappy with the CS overall. Sent from my One S using Tapatalk 4 Beta |
