AR-15 BS Thread

I missed out on that last opportunity. Still on the hunt.

 

strictly want BCM or just looking for a quality lower?

 

Lower is built once I get past Christmas I picked a bcm 14.5 quad upper mid length

 

great choice. Their QRF is one of the lighter quads on the market. Added bonus that it uses the same barrel nut as an mlok from them so if you hate it just swap it out.

 

Well, I was hoping to get a BCM lower.

 

It sure seems like they like to concentrate on their uppers.

 

gotcha. Rooftop has some nice LMTs and LWRCs that’s why I was asking.

 

makes sense. Their lowers are just a lower with their rollmark. The uppers are definitely really nice.

 

I have several uppers and they do seem to push uppers a lot. All of my uppers are paired with PSA stripped lowers that I assembled with Geissele triggers. It's been a great success.

 

sounds like solid setups where you spent money where it matters and saved where you could.

 

Alright so I’m trying this. I haven’t been able to shoot yet but we will see

 

Welcome to the tribe!

 

So far it feels pretty good. BCM upper so quad rail not real bulky. I’m trying the cheap rail ladders to see how they do hell they may fall off I guess I’ll see. 14.5 with their mod 3 comp pinned

 

What are the advantages of the MK2?

Trying to get ahead of the learning curve Before I purchase

 

Featuring BCM’s Patented MK2 Upper Receiver
This proprietary design offers enhanced rigidity over the USGI product. The increased rigidity limits barrel deflection which aids in consistency/accuracy. Less flex also reduces premature damage, wear, and failure of bolt lugs from misalignment. A gas expansion chamber is machined above the charging handle track, combined with dual vents machined at the rear (each side, above charging handle latch) help to redirect and vent gas away the shooters face.

 

I just found out that my local gun shop cannot accept this complete lower because it doesn’t already have the California compliant magazine mechanism installed. They can only accept stripped lower receivers….Which I have yet found a way to get a BCM one. So frustrating.

 

Other than having "BCM" engraved on it, the lower isn't any different than any other. All AR lower forgings come from one or two mfgs, and the CAD file used by the CNC machine to finish it is the same one everyone else uses.

Their LPG might be better, no idea, but you can buy that separately.
