hey guys, whats the best internal upgrade that i can add to my 16 inch ar? i have most of the sexy appearance things but is there anything i should add to the guts of the rifle? is there anything to make it run smoother or give it a longer life. btw its a new stag. thanks, brandon |

Well if you have a M4 collapsible stock on your 16" you could drop $25 on a 9mm Buffer (see them at RRA) into your rifle, which will slow the cycling, reduce the felt recoil and improve the reliability. Of course if you are running the A2 type stock this is not an option. LMT and LW both sell "enhanced" bolts IIRC, (I'm running two LMT enhanced bolts - one 223, one 6.8mm) Quality 2-stage trigger is always an advantage, IMO. mike |
+1 at the very least swap out the silver spring and blue extractor insert (for rifles) with the copper spring and black extractor insert (for carbines)... bravocompany sells a nice little kit with the springs, inserts, and the o rings... |
Were is a good place to get this "O" ring? Thanks |
Daa Bravocompany, guess i should read all the post first  Thanks

The color of insert has nothing to do with rifles or carbines. The gold colored extractor spring is used on carbine currently. In my opinion, the best thing you could do is replace your Stag bolt/carrier with a Colt piece. |
The inserts definitely are different, the blue was the lower density unit used in rifles and the black for carbines. Recently produced FN M-16's are showing up with the black higher strength units in them as well, but previous to this they had the blues. |
+1 - That's the most cost effective internal mod you can do. The LMT Enhanced bolt carrier is a great mod for a Carbine, IMO, but it costs... |
I'm sorry but your wrong. Blue units were spec for both rifles and carbines from about 1984 up until about 1998. After 1998, black was used in both rifles and carbines. In 2003, the heavy gold extractor spring began to appear in carbines. With black inserts still being used in both carbines and rifles. |
LMAO!!! Tell me this is a joke! Those are identical pieces of equipment! LMAO!!! |
Get a 2 stage trigger if its for SD or LE use too. THAT is the most effective upgrade for the internals of your AR. It is a real world improvement you can tell the difference of. A 9mm buffer would be behind that. |
Buy an LMT bolt carrier group(has the good parts mentioned above already in it and is MPI tested) and keep the Stag bolt and carrier for spare parts, especially if you end up with a MIAD grip with a spare bolt/firing pin insert  Stick to a single stage trigger if you are using this as a battle rifle or for SHTF backup |
Stag carriers have those weak stakes on the key that look like they've been done with a chisel and their bolts are not up to spec either. The bolt/carrier is the heart of the rifle, and I wouldn't skimp on it. |
Its funny you try to get me, but you suggest using a 9mm buffer which is totaly unecessary. |

I would like to know how a CMT bolt is not up to spec. Its the same damned thing. Same materials, same construction. Restake the CMT if you like, dont buy a new one. IT IS THE SAME PART WITH IDENTICAL PERFORMANCE. It is not any more reliable and the user cannot tell a difference. A 9mm buffer makes a REAL difference in perceived recoil. Can yo uperceive any difference in a Colt vs CMT BCG in your rifle? I think not. If people would use a little common sense it would go a long way. What will you gain from a Colt BCG over a CMT unit? They are identical in reliability (once you restake it) identical in materials, identical in contrstuction, identical in coatings, etc. The end user will notice ZERO added benefit. Its like buying a new car because it is a Chevy instead of GMC badge when the ONLY difference is the badging. It is absoloutely stupid. |
What 2 stage triggers have you had that failed? Or is that some regurgitated internet commando stuff? We all know how the 2 stages in WWII were not up to combat duty.  Why should this guy get a NEW bolt and carrier when he already hasone he can stake better if it needs it and put an Oring on the extractor? |
The only good reason I can think of would be if he wanted the LMT enhanced carrier to delay unlocking and ease extraction. |
Some people don't have the ability to restake a carrier. If done properly, a MOACKS tool is $150ish. And not worth getting if you own just a few ARs. I don't even have one. A screwdriver and mallet is not a prefered way to stake a carrier. I want to see proof that a CMT unit is identical to construction to a Colt. If they skimp on their staking, what else are they skimping on? A staking tool for production would be less than $1000 and they can't even invest in that. They can't perform a basic stake, so what makes you think they will go to the trouble and expensive of using the proper material or have a proper heat treatment set up which is thousand of dollars? Whats the carrier material? 41XX series? 86XX series? Heat treatment? I want to see how they are "identical" then I might let you have this point. A 9mm buffer is not needed. Look, Colt has experimented with or put into production about 20 different weights of buffers over the years. We are currently using what is believed to be the best combination of reliability and recoil managment. Do you know better than Colt? |
| I run a LMT Enhanced Carrier(FA) with either a Stag or Bravo Company Bolt with black bumper and Crane O Ring in all my carbines. BTW, the LMT Enhanced Carrier is the best thing I've ever did. I have had zero extraction issues and my rifles have been reliable as hell with all kinds of ammunition. With a Crane O Ring and black bumper IMO, the type of extractor springs don't matter too much. I use a combination of standard , CS and Bravo Company's super duper extractor springs and the results have been the same for me. One good thing about Bravo Company's Spring is that it's so strong that no Crane O Ring or D Fender is needed. |
I definitely can feel the difference between the two. |
Scott, what weight buffer do YOU recommend? I'm not giving you crap or trying to bust your balls. I just want your opinion. I've read numerous posts about a 9mm buffer and want to know your opinion. TIA. |
For a general purpose carbine, I would run an H buffer or go heavier with an H2. A 9mm buffer is to make the reward movement of a blowback 9mm carrier not so violent so it isn't so hard on the gun. |
