Colt or LMT. I wouldn't go much beyond those.

I have a Rainier BCG. Works great, everything looks good after about 1k rounds. They make good stuff.

The same company that made the Rainier BCGs made Dennys BCGs. I have used Rainier Products before specifically their uppers and I have never had a bad experience with them. For the price range I would say it is a solid BCG. I have ran DSA, Rock River, LMT, Young MFG N/M and JP stainless tactical BCGs and I have never experienced a malfunction from any of them. Clean em dry and shoot em wet and you should be good with the Rainier. Dont be afraid to go outside of what people say on here. Not knocking anyone that believes in colt; but I dont buy into all of the Colt hype. They do have longevity in the AR buisness but it is also 2011 and manufacturers are able to build quality components.

So Rainier is a no go? Why?
I can definitely find LMT but haven't really looked for Colt BCG's. Why is the LMT so much better than Rainier? Also, I can't find any specs on the LMT stating whether or not it is HP/MP tested and all that good stuff. |

I am using 3 Rainier BCG's in 3 different rifles. I have had zero issues. They are HPT/MPI tested like the others so I don't see how you can go wrong with using them.

So some say No to Rainier and others say yes... To me from the specs they provide they seem like they are comparable to a BCM.
Oh and I definitely don't have the money to drop on a Colt BCG. |

The two guys above just told you that they are all good to go. As long as they are to mil-spec, you good to go. Some guys are sold on one or two brand names. How one can claim one is better the the other is beyond me.

...Some guys are sold on one or two brand names. How one can claim one is better the the other is beyond me. Because not all parts are created equal, and not all 'manufacturers' put out the same level of quality or same specs in a given product (that looks identical to the next). Maybe not you, but some people get a little funny when certain brands are mentioned, and go into a "you're just buying a name / i don't buy into the hype / my brand x is 'just as good as'" thing, largely because they have limited experience and/or they base much of their opinion on what they read on the internet (hearsay). BCM, Colt, and LMT have shown a level of competency in producing a product that has given ME the fewest issues. They're about the only companies whose major components I'll buy anymore. I've never used Rainier's bcg, so I can't comment, however if they're just getting them from Y/M then I'd pass. Back to the op, if the Colt is too much (it's not *that* much more..), then get an LMT for around 140. Same $ as everyone else. |

The Colt BCG's that I saw were over $200 which to some is good bit more. The extra money could be used for a rear sight or other parts.
Oh and is the LMT HP/MP tested and all the important stuff? |

My experience with Rainier products has always been good. I don't feel "parts are parts". Actually might be considered somewhat of a BCM fanboy. Using a Rainier BCG wouldn't bother me though. I feel your pain on the lack of availability on BCM BCGs. I got tired of waiting too and bought a couple $109 Spikes BCGs for Bravo uppers and am confident they will perform just as well. I've been hammering them good and hard and so far I have no reason to think otherwise. JMO though.

thanks for all of the replies fellas. I haven't decided on a particular BCG yet but have another question since we're on the topic of BCGs.
What's the difference between a semi and a full auto BCG. I know that the full auto BCG has a reinforcement at the rear of the BCG that is the same length as the top while the semi doesn't. Is there any benefit in buying a F/A over a S/A? Will a F/A BCG work fine in a S/A rifle? Thanks |

A FA BCG is heavier and slows down the cycle rate. They work fine in Semi autos. Hell, many of the major manufactures use FA BCGs in the semi autos.

The problem is that for some of us (like us in WA state) state laws can be poorly written. According to WA state, if one has the option to use semi-auto specific parts, they must use it, LOL! Thing is, plenty of Colt rifles and other brand rifles are sold in this state with FA BCGs. I use semi-auto bolt carrier groups on my personal guns since I like to dot my "i"s and cross my "t"s, but FA BCG usage is generally not a big deal, for or against. Most folks get most of their extra mass from heavier buffers anyway, and on the flip side I don't think anyone's ever been prosecuted just for having a FA BCG. Of course, i'm not a lawyer and this just my opinion

Palmetto State Armory is offering mil-spec MPI bolt carrier groups for $120, and you have the option of buying a charging handle for another $10. Spend $190, and shipping is free.
A friend of mine and I have purchased a pile of PSA parts lately, and we have been very happy with the quality of the parts and the service. They are running killer deals on complete uppers ($400-$430 for 16" and 18" 5.56 and 6.8 flattops), and LPKs with Magpul furniture (and Ergo if you prefer). For instance, right now they have some in stock complete 14.5" 1/7 5.56mm (with pinned suppresor/hider to make 16") upper assemblies (fixed FSB, BCG, and M4 handguards) for $400. Extra cost options: quadrail (about $100), MOE handguards ($20), and rear MBUIS ($50). |

Here's a thought. Let's completely abandon the terms semi-auto and full-auto when referring to bolt carrier groups for our "Modern Sporting Rifles". I suggest we all immediately switch to "full-figured and slim-line" configurations!

The Rainier BCG is GTG. Not only are the specs identical to the BCM one, they offer a lifetime warranty and will replace it if it breaks. Rainier are an excellent company and stand by the products they carry. It is also cheaper than the BCM one.
I really have to commend BCM for their complete and utter dominance of the BCG market....they have had one slick marketing campaign. Fact of the matter is, 99% of "Brand" companies make nothing (or at best, a very very limited amount of stuff) themselves in house. 99.9% of bolts all come from the same few production factories; the only difference between the "Brands" is the QC standards that are demanded by the brand company. BCM has imposed strict standards and have excelled at letting the world know it; others (such as Rainier here, or the Palmetto one) have equally strict standards and have stated as much, but the BCM internet momentum has a lot of people thinking BCM make all their own stuff, and it is BCM or nothing. And fair play to them, they are doing great in a competitive business. However, they (and LMT/Colt etc) are far from the only game in town. |

I have another question....not about BCGs but the upper halfs themselves. Are LMT's uppers just as good as BCM? I ask because 1) I don't particularly like the big white "BCM" billboard on the side of the upper reciever (just a cosmetic thing for me not too huge of a deal) and 2) If the LMT upper is just as good as BCM then I could just order everything I need from Rainier and save on shipping.

I see....given a complete basic carbine length upper like like, I wouldn't differentiate between either LMT or BCM; I'd buy whichever one was cheaper to be honest - both top companies.

Rainier stuff is good stuff..... But they also handle LMT which is also good stuff..... Either way you're good to go...as long as you have a back up bolt.... Two is one...and one is none. |

My Rainer/Denny's Thunder Bolt is approaching 9K rounds combined SA/FA without a problem.

I wouldnt hesitate to use anything from Rainier, they have a damned good reputation in the business. Although Ive never bought from them, I would. No particular reason I guess.

I've spent quite a bit of money at Rainier Arms, both online, and at their store in person. They are a good group of people who take care of their customers. They won't stamp their name on anything that isn't good to go, and they won't stock anything on their shelves unless they would use it themselves. If for some odd reason you do run into a problem with something of theirs, I know they'll make it right for you.
Buy with confidence. |

Specs: BCM 16" M4 upper Magpul MOE handguards Magpul MBUS rear sight Rainier Arms BCG WOA Charging Handle Stag Arms lower reciever DPMS LPK ACE Skeleton stock Since this thread was about the Rainier Arms BCG I'll go ahead and state that it seems like a high quality BCG. It was a little stiff when I got it but I cleaned it and lubed it up with some CLP. It loosened up a little bit but not too much. I'm sure it'll loosen up after firing it a little. Here's a pic of it all put together let me know what yall think. I'm thinking of replacing the ACE stock with a Magpul MOE stock.
