Interesting thread, purehavoc. Nice to see Spikes, PSA and LMT close up. We should add pics of other BCGs. I have BCM and DD so will have to get the camera macro mode going this weekend.

LMT usually makes a great BCG but you do have to specify the M16 not AR-15 carrier. The light staking does bother me. If we do put up more pics it would be good to get a good view of gas key staking.

Would be nice to get a sticky with up close " Macro" pics of all the different bolts . DD is one on my to find list , unfortunantly nobody had one in stock when I was looking and I couldnt wait as I had another upper on the way.

I just picked up my DD M4v3 today. Maybe I'll contribute picks of the BCG...well, when I'm a bit more ambitious. It's a well staked M16 of course. Mil-Spec+ is their motto, after all.

Got home and discovered the vertical foregrip was cracked, so that part is going back to DD in the morning. I replaced it with a Magpul AFG (which I prefer) I had sitting around. I'm loving the lightness of this rifle. Maybe I'll get it out to the range this weekend. I think this thing will stay stock for the time being, without any optics.

My Spike's M16 BCG also showed up in the mail today. Honestly, it's pretty tough to beat their quality for $120 or so. It's going in my now "beater" DPMS Sportical...which has actually been quite good to me, and is also a nice lightweight little carbine. While somewhat expendable, it's a keeper for sentimental reasons. And a darn good friend.

Once I get my BCM build together in a week or so, I'll get pics up of the pair. All the remaining parts come in this week.

Yeah, the BCG in my LMT CQB MRP 16" certainly does not look like that.

Finally got around to pictures of my BCM and Daniel Defense BCGs. The DD is an older version bought in 2009 that isn't laser etched with DD and the bolt isn't marked HP MP like the BCM which was bought a few months ago. The BCM gas key staking is a little better but all in all the DD is acceptable. I understand the current DDs are now the equal of BCM but haven't seen one. Even though the old DD isn't marked DD did claim the bolt was high pressure tested and magnetic particle inspected. Staking is the only issue I see with the older DD though it is not bad.

I thought about throwing in my ArmaLite BCG but it looks just like the DD except it has an AR-15 style carrier like the LMT at the top of the thread and the bolt has a relieved lug opposite of the extractor. (That lug isn't used.)

In the pictures the BCM always is on top.

sweeper22, I'd love to see your new DD BCG vs. my older one. Kinda wish mine had laser etching like my BCM. DD started that in 2010 I think. Of course the etching doesn't affect performance but I bet your staking is better and that your bolt is marked HP MP.

At the risk of sounding like the AR noob I am, what is the difference between an ar bcg and m16 bcg

Look at the LMT carrier which is the one in a vertical position. Look toward the end of the LMT and compare to all the others which are M16 carriers. Note the LMT is cut shorter on its left side. Some really pathetic AR-15 carriers also expose the firing pin (not LMT though). It's wise to get a proper BCG in the first place since it's such an important component. Now LMT is a very good BCG but they do sell both kinds of carriers so something to watch for.

I think this link will provide the answers to that question.
