BCL lower with BCM warfighter LPK

[Sorbz62]

I bought a BCM lower from TNA (great service, no complaints) a while ago and recentky bought a BCM warfighter LPK. Today, Ive been installing it and found 2 issues:

1. The bolt catch detent/ spring hole goes all the way through the frame so the spring falls out.

2. There is no hole for the rear takedown pin spring and detent.

Now full disclosure is that I've emailled both BCL and TNA but I thought somebody on here can help me or give me some advice. Maybe there are easy fixes.

Cheers,
Jim

Did you buy a BCL or BCM lower?

On your BCL, I think there's a plunger that goes into the bolt catch hole first that’s a proprietary part, then the LPK provided spring, then the LPK bolt catch plunger. You’ll also need a long set screw to hold the bolt catch in place instead of a pin, or you’ll never get it out.
The rear takedown spring and detent are located on the right side next to the selector switch detent and spring, both held in place by the pistol grip.
Everybody wants to be different and unique. Cheers.

Did you buy a BCL or BCM lower?

I bought the mystery box from TNA which came with the BCL lower and upper.

Hey Sorbz62 which mystery box did you Order?

BCL lowers use Ambi bolt release. You will need their Ambi paddle and plungers. Bolt catch is standard I believe.
