Silly question but why do you want a light bolt carrier? What use?

Silly question but why do you want a light bolt carrier? What use? View Quote Our shop 300 blackout is loaded up with G2 Research subsonic Trident rounds. The rounds are crazy deadly BTW. Even at subsonic velocities the rounds open up like a propeller! We wanted to keep this particular rifle as short as possible, so that meant no suppressor to help cycle subsonic rounds. No matter how much we opened the gas port we could not get the rifle to cycle subs reliably. We were able to fix this by using one of our Lightweight BCG's. Lightweight BCG's have particular applications. They're not for everyone but can be very helpful in certain situations. |

Silly question but why do you want a light bolt carrier? What use? View Quote In a machinegun, hammer timing is controlled by the auto sear and immediately drops the hammer as soon as the carrier closes. In a high cyclic rate semi auto (Such as a BumpSAW or Binary trigger), you can make the trigger release the hammer before the carrier has had time to fully cycle. My BumpSAW routinely runs ~1000RPM. That's faster than an M16 rifle (600 to 700RPM) and faster than many M4's (~900RPM). I use a lightweight carrier and heavy spring so the carrier cycles ~1200RPM and always closes before my finger sets off the trigger. With a stock carrier I would occasionally get a dead trigger. The hammer hit the back of the carrier before the carrier closed and didn't have enough force to ignite the primer. In a binary trigger you also want a fast carrier. Given a .15 split time, your looking at 450RPM. But in a binary your getting two shots off for every pull, so your up to 900RPM. Now, get one extremely quick split - say .12, and you just touched 1000RPM. Most people can pull a few splits in that .15 to .12 range (and Jerry Miculek can hit .10). So keeping your cycle rate above 1000RPM eliminates problems and lets you keep the machine gun rate of fire without the machine gun parts. |

Ordered one late last night. As much as I love my SS JP LMOS in dream build # 2, I want to do a light carrier in dream build #1 but willing to try yours instead of another JP. Looking foward to giving her a whirl.
Thanks for offering this at an increadible value. 9310, 8620, Nitride, MPI... all the key terms that interest me, that's for sure! Rock on, Jim Edit: Oh yeah, the "you break it, we replace it" is certainly a nice touch too. |

Cool just bought two. I hope the keys are installed properly, meaning locktite, torque and staked all to spec. AIM LW carriers are notoriously not...

Damn! Out of stock.
Any chance there will be more at this price? Thanks |

Looks very nice. Looks like my AIM LW at same weight. I'd try one if they're still on sale if I do another LW build soon.

Well sh*t, I stumbled on this thread too late. Everything is OOS.
Standing by. |

I've never used a light bolt carrier and I bought a couple for a long awaiting project.
The build is a 1:12 WOA 16" mid-length gas system (I bought the barrels on sale some time ago). I will be shooting 40gr V-MAX 223 Fiocchi ammo. Now here are the questions: (1) I assume I want a gas block to regulate the gas - right? Otherwise I assume the bolt will go supersonic and trash the lower parts. (2) I will have a standard stock - what do I use for buffer and buffer spring? Standard buffer and lighter spring? Thanks for your help. |

You may need the reduced power action spring to ensure that the action doesn't cycle faster than the rate at which the magazine can make the next round available. |

Thank you both for the input:
I am thinking of the following for the standard Rifle stock: (1) Adjustable Gas block (2) Buffer: Tacom Ultra lightweight Riffle Buffer http://www.tacticallink.com/Taccom-Ultra-Lightweight-Rifle-Buffer-for-AR15.html or the J P ENTERPRISES - AR-15/M16 LOW-MASS RECOIL BUFFER http://www.avantlink.com/click.php?tt=cl&pw=55963&ctc=j1nd00se1w00zk8a00y51&mi=10077&url=http%3A%2F%2Fwww.brownells.com%2Frifle-parts%2Freceiver-parts%2Frecoil-parts%2Frecoil-buffers%2Far-15-m16-low-mass-recoil-buffer-prod27116.aspx (3) Buffer Spring: David Tubb's Lightweight Stainless Steel Buffer spring for AR-15 platforms http://www.davidtubb.com/ar15-buffer-spring-stainless Any thoughts if OK to go? |

I got my two in. They look great. Haven't built my rig I intend to use it in yet, but the machining and finish look excellent.

So, is this a slickside carrier, no forward assist serrations? Or does the solid side contain them. No pic available of the other side.

Just picked up my shipment - very nice bolts indeed!
This is going to be my first light bolt build. |
|
Chewbacca: what will you use for buffer, buffer spring and gas block?
|
|
|
|
|
I am curious. The bolt carrier is covered in a Nitride treatment (nice).
Can I assume the Carrier and Gas Key are not chromed under the treatment? Customers: if you bought just the carrier - whose bolt are you using? |
|
|
Buy with confidence from Right to Bear. I've bought quite a few things from them and they're VERY quick to ship. I once had an issue with a nitrided bolt that started to "chip" at the cam pin hole. Rob sent me a new bolt ASAP. Excellent customer service which has me checking their site first anytime I need something.

What cut is that on the carrier, regular semi AR cut, or SP1 (rll compatible) cut?
|
|
Looks pretty good. Any issues with the carrier breaking after a few thousand rounds ?

Back in stock notification came this morning... Nailed another one!
Thanks again for producing and offering a great LW carrier! Rock on, Jim |

Quick question: does the carrier extend past the base of the gas key to prevent sediment from entering the upper receiver port (behind the carrier on a closed bolt)?
The AIM lightweight bcg leaves a quarter inch void, so I would like to replace it should your product meet this requirement. Also, would you sell the carrier and key together unassembled (call in) to make it easier to install a RCA adjustable gas key? |
