Here is a link so we all are on the same page.
http://www.spikestactical.com/new/sss/bolt-carrier-group-spikes-lightweight-nickel-boron-hptmpi-m16-bcg-556-p-1067.html Is there any disadvantage to one of those in a Varmit Rifle? The gun will also be used in some local novice matches. I want light recoil so I can have a easier time with follow up shots, and I figure this will help as I have a JP light mass buffer and a wolff extra power spring. I plan on adding a compensator as well. My father in law has problems with coyotes during the summer, and wants me to take them out, which I plan on doing. Anyways all information will be helpful. |

Don't get me wrong. Spike's appears to take great pride in their products, and their quality shows. But you can make quality gimmicks for no other reason than people will buy them. There is absolutely no reason to install one of those things in any of your rifles. And it isn't a bash on Spike's. A lot of AR stuff makers engage in the same practice.
Some people simply can't see through all of the cookies and bullshit out there. Those are the people being targeted through razzle and dazzle marketing. |

There is a reason, its for 3-gun and competition shooters looking for every edge possible. You run a lighter BCG, a carbine buffer (or an even lighter aftermarket one) and a adjustable gas block, and turn the gas block down to where it it is just enough to reliably function. That gives you a soft shooting rifle that is easy to shoot fast. To the OP- I'm not sure if you should be using the JP low mass buffer system in your build, that is typically something that is also used with an adjustable gas block. I don't think the things you are doing really fits in with varmint builds. Also you mention using a heavier hammer spring which effects trigger pull. I'm assuming you have an issue with light primer strikes and it is not a 223/5.56 build? The Jard and RRA are known to work with 50bmg primers, have harder strikes than factory ar15 trigger. They are both lighter and more suited to your build. Your direction seems to be off for a varmint build. |

On another forum a member is using a single lower for two caliber uppers. He has a heavy buffer in his lower which works with his 5.56. It is too much buffer for his 300 Blackout. So in the 300 he will use a light BCG to make the total mass lower so the 300 will cycle on the same buffer.
And as stated tuning for low recoil can take a whole bunch of paths which could include a low mass reciprocating system. Although mostly I have read that a high mass properly sprung system can reduce recoil. This BCG with the JP contained buffer and a whole bunch of springs just might be the ticket for someone trying to accomplish some certain goal. What is the cost? Is the cost worth the knowledge about how it works? That is what I did with a Geissele trigger. Bought one. I don't care for it as I have determined I do not like two stage triggers. Does that make the trigger bad? No, it just is not for me. I like to learn all I can by studying from others experience. But there are some things I just have to try for myself. And because it was a Geissele selling it is very easy. Total cost to me less than $50. Can't buy education for much less than that. |

Spikes makes good stuff. I have one of their regular BCG's. I'm just not sure I can get past all of those holes.
That being said. I'm using 2 JP low mass carriers in .308's, and love them. I've been toying around with trying one in 5.56. But honestly I believe that I will go with a JP. Is price the reason you aren't looking at a JP? Yes they are more. But all 3 BCG's I have from them are some of the smoothest I own. I have BCG's from, BCM Colt, several JP Spikes Young's NM- Both .308, 5.56 Those are some of the nicest groups out there in my opinion I'm building a Noveske, with the type 2 lower. Think I'm going Lija for the barrel. Oviously, Geissele trigger But on that toy build I'm going with JP LMC and their captured spring setup Don't get me wrong I'd like to try a Spikes  , But I just don't want to spend the money on it only to find out I don't like it.
With the JP, I know what I'm getting. 
DAMN this hobby is expensive!

To really get the full advantage with your varmint rifle you will need a adjustable gas block.

And my trigger and hammer are tuned for a nice easy snap. A tad bit lighter hammer spring. I also have no upper at the moment, I am doing this once piece at a time. I am making a 223 upper, as the biggest thing I am going to shoot is a coyote. And I am trying to make a gun that follows up easy, and something I can at least compete against my dad and his SVD. I am also looking into one of JP's adjustable gas blocks for this build, as I want to be able to fine tune this gun, also I am going to be handloading the rounds that will be shot threw this. But it seems like Spikes BCG may be to extreme for my needs, anyone recommend a lighter BCG thats decent price? Hell I may just go gas piston system lol |

Granted I know I am going to catch flack, but I call NATO and 223... 223. I only mess with 5.56 chamber and 223 Wylde. But I reload 223, and I size 5.56 down to 223. So I am not to worried at all about it cycling. I call em all 223's as well unless someone is asking a specific question that I need to point out the difference. |

Not sure why you are looking to a light carrier to go with a heavier than stock buffer spring. You haven't bought an upper yet, and you may not have enough gas to even cycle it with a heavy spring, let alone worring about during the gas down. |

You haven't bought an upper yet, and you may not have enough gas to even cycle it with a heavy spring, let alone worring about during the gas down. When running a low-mass system (light BCG, light buffer and adjustable gas block) an extra power buffer spring helps ensure that the next round is stripped from the magazine reliably. To the OP - The Spike's lightweight BCG is good-to-go. I'd suggest the SLR Rifleworks adjustable gas blocks, though. They give you a wide adjustment range without needing to use locktite or set screws to make sure your adjustments don't move on you. |
