if you went with an A2 you could build build a pretty close SR25 look alike.
Guys were wondering what my BCL102 weighed in at...
Supposedly 8.9lbs for the bare rifle, plus the GG&G 35MQD mount & Elite 6500 1.25-8x32 scope, it is 10 lbs 8 & 5/8 oz.
Add a IMI mag with 5 rounds that weighs 10 & 7/8 oz...
So the rifle is a little over 11 lbs 3 oz with a 5 round mag as I have it set up.
Cheers

P.S. Yes, that is my wife's kitchen scale in the pics, but she's never on CGN anymore, so I don't have to worry about it, chuckle!

You have the same idea as I.
From what I can determine there are two designs of bbl extension and mating bolts. DPMS and Armalite, headspace is determined through the interface. There is much info to sort through on US forums.
No one has been able to verify if BCL uses one of these or their own design.
Incorrect headspace leads to problems.
I don't think this an insurmoutablre problem and will be investigating when my "second gen" arrives at the end of the month,(?)
It looks like weight savings of over a pound could be had.
This is what I would be interested in.

I'm also curious as to why NEA / BCL chose to use a midlength gas system as opposed to a rifle length like we see on many other 18" barrels.

Yup working on order #2 since I couldn't fit it all in the first one ....lol...
Im trying to figure out what Buffer and spring to grab as well if I should grab a spare bolt. Looks like the Brownells rod is only 46$
They are a few different buffers and spring combos, Does the 102 use a rifle or carbine buffer ? Love the JP springs, I used them all the time in my AR builds.
From what I have been able to gather so far, the BCL 102 may be based on Armalite pattern.
The 308 bolt is longer so some adaptations are necessary and Mfg tackle this differently.
Armalite Rifle length-same extension as AR15 rifle with Armalite rifle buffer(5 3/16") and 308 rifle spring.
Armalite Carbine length- longer extension than AR15 carbine with h3 carbine buffer and 308 carbine spring.
DPMS uses a shorter carbine buffer to get around this.
I'm still researching this and it would be nice to get some measurements from parts on the rifle.

Just thinking out loud, but could be a reason why the surplus mg ammo has a higher rate of stoppages.
I'm having a hard time finding .875 adjustable gas blocks.

The only one I've come across is by Seekins but I haven't looked too hard.

I'm starting to wonder if the reason lighter 7.62mm NATO surplus type ammunition doesn't feed as reliably is due to light projectiles and a very odd combination of a short barrel (18.5" for an AR10 design is pretty damn short) and a mid length gas system. Mayhaps the short dwell time is not allowing enough pressure to knock the bolt back as far as it needs to go with enough force?
Maybe.
My experience with my MWS (16") and SR-25 (20") indicates that most (there are exceptions) store bought ammo that isn't 7.62 NATO surplus show signs of pressure and beats the sh!t out of the gun. Some of it does quite OK as a hot loading, but the majority I've tried did not. I think GMM is a mild loading, and it shoots pretty decently in most anything. From what I've seen in this thread, the BLC-102 is following this trend with the GMM ammo.
It is known that binding of the carrier key on the gas tube can be a cause of stringing - this issue alone shows that while the AR impingement gas system isn't comparable to typical gas systems, I don't think it is the exception some believe it to be.
Powder burn rates, round feeding from a mag, crimping & neck tension all play an arguably larger factor with a semi (and the AR) than they do with a bolt gun.
I'm thinking it has more to do with brand spanking new chambers that may be a tad sticky, some limp wristing from guys who don't otherwise own this style of rifle, and perhaps feeding them questionably suitable ammo.
Were these things shipped with a cleaning kit?
How many of these guys have a proper AR-10 chamber brush, or used it on their rifles?
My WW Ar-10 came with a 16" barrel with mid length gas system and had no problem shooting 7.62 nato ammo
