I am using my RR Car4 for a patrol rifle. I just put in a T2 buffer from Spikes Tactical. Would a M16 bolt and carrier bennifit me as well. What is the idea behind upgrading to a M16 bold? Any down falls? I'm clueless about this.

| No malfunction issues at all. I was just told by someone to get a M16 Bolt. I assume it has to do with the weight so the cycle is smoother and better follow up shots... Again I am clueless about this the buffer was nice to add a lot less felt recoil my follow up shots are much tighter. |

Is it worth the money or will my stock RR bolt do the same thing? What about just getting a crome bolt? The "M16" bolts from BCM,LMT and Daniel Defense are made from the better C158 steel(rather than 8620),they are individually HPT and MPI tested(rather than lot/batch tested) for durability and quality,also the extractors are machined from tool steel.Thats the reason to upgrade the bolt....better and known quality.If the rifle is to be used hard or for defensive purposes I'd certainly upgrade the bolt to a BCM,LMT or DD,and keep your RRA bolt as a spare. As far as the carrier is concerned,if its a AR15 shrouded carrier(which Im sure it is) there is only about .40oz. difference in weight when compared to the full mass M16 carrier.I'd just make sure the gas key is staked properly and save a bit of money for something else rather than replace the carrier.. |

If your gun runs, don't screw with the internals. Seriously...when you start stackin in parts from different vendors, you get problems. Tollerances are not 100% standard in the industry and certainly not with vendors that don't build to mil-spec.
If you want to upgrade...great, get a Colt LE 6920. Otherwise, don't mess with the internals on your duty rifle. It ain't like a gun used in games where you get a do over if you have a malfunction. Add a rail (like a LaRue 7.0), a light (Surefire), and an Aimpoint (in a LaRue mount). A sling would be good as well....viking tactics is the place for slings. |

I missed the "patrol rifle" comment.That said I would not make any modifications to a issued weapon or one that has been approved for use if it was not mandated by the department policy.Such modifications should be handled by the armorer as well.Im an ex-LEO and know how department policy can be in regards to this and you run the risk of having your ars handed to you when called in on the carpet.
As far as a tolerance stack involved in changing bolts...I have not seen this to be the case with any quality assembly.That said Ive never owned a bottom feeder builds either. If there is a tolerance issue within the weapon that would prevent the use of a quality industry standard bolt assembly I'd say there are far more issues to be concerned about with the overall quality of the weapon and it should be returned or replaced as its not to be trusted in the first place. Considering the fact that most of these manufacturers buy the components from outside suppliers that are likely to change at a moments notice as supply and demand dictates,the chances of getting a factory replacement bolt from the same supplier now or in the future is a shot in the dark.So if the tolerances and specifications used by the manufacturer are an issue now,that would raise questions about future repairs as in a bolt failure,which would be no different than upgrading a bolt to better quality and durability. Replacing a bolt,either to upgrade or one that has failed is as simple as assembling the BCG,checking headspace and test fire to check function and reliability.If the barrel extension and chamber are so far out of tolerance or spec that it would prevent this it needs to be returned to the manufacturer and replaced with a better quality assembly. While I do truely believe in the "if it aint broke,don't fix it",I do believe that taking a pro-active stance in making a simple bolt upgrade and staking the components as required is a positive move in the right direction for a lesser quality build that is to be used for heavy use,or as a defensive weapon.As is a respectable test fire to assure that the weapon is reliable. Upgrading a shrouded AR15 carrier with a full mass M16 style carrier for no other reason but to simply gain .40oz. of weight in the system would be exceeding the need. Thats my unprofessional opinion a on the subject though. |

PACC508,
Not to flame you but to inform you about your nomenclature. There should be no difference between an AR bolt and an M-16 bolt. The difference is in the carrier. The carrier has a little more weight and as stated before, some people do it because they can and others use it to help cycling/functioning due to the extra mass on the carrier. |
