    6x6.8 spc gas length

    It will barely stick out. The back of a rifle length is 12 3/8. +2 is 14 3/8. 1" long GB =15 3/8". You could go +1 to keep it completely concealed.

    10.5” - 12.5” 5.56 barrel question

    +1 Going to any gun forum in an attempt to help is a waste of time. It doesn't matter if you've been a gunsmith for 40 years and they have had their rifle for a week they will still argue or discount your experience. That said the ARP 12.5 is really 13", changed after the first batch to make it...

    New US Made M14 Lothar Walther barrels with new ICR rifling. 24"to 26" velocities out of a 22" barrel.

    There are several brands of barrels with different rifling configurations that are faster than most. Years ago the Rock 5R barrels were known to be faster. The 5R AR15 barrels Blackstone Arms is selling average 90fps faster than other AR barrels but the 14.5" I shot Saturday was 130fps faster...

    Best 12.5 barrel?

    Tested another 14.5" 5R barrel today, ave 130fps faster than the 14.5" BCMs I have tested. I'm good with people thinking velocity doesn't matter.

    Best 12.5 barrel?

    I bet most are using M193 and m855 just like everyone else.

    Recommend me an 18" semi-automatic 5.56

    All of those look high priced as you said. I removed a few I would not touch, others I don't know about. As others have said add-BCM(more of a fighting rifle), FN(more of a fighting rifle), LMT

    New M1A scout. What should I know?

    #1 You already have that figured out, that barrel mounted rail was a STUPID idea. Same receiver mount is still the best. The barrels may be raw untreated steel, borescope the barrel to see if it is covered in rust. Then I think you will need to lap the crap out of it.

    Plate Carrier vs Vest

    With the Bidens giving them money do you think they need to sell plates for funding? R&D really? I'm not giving them feedback. 90% of everything sold at walmart for the last 20 years has been made in china, if we search your house how many things would we find made in china? Nice try but you...

    Plate Carrier vs Vest

    Old thread I know but things are changing-Best deal on plates right now, Buffman tested these plates on youtube. They have edge to edge protection and run about $200 a PAIR, weigh 4.5lbs I think depending on size and cut. Yeah they're made in china but less than half the price of others and...

    Plate Carrier vs Vest

    Old thread but the Javlin A JAC has some features that others don't including plates load from top . Before I had to mix bags from one company and cummerbunds from another and placards from another. They aren't advertised much but worth a shot

    Nothing like a brand new rusted barrel, didn't even need to scope this one! :)

    Try the 80 ELDs with H4895 seems like 24.8-25.1gr. Check the valkyrie forum for "little red rockets" the guys over there found that load produced enough velocity(3000fps) to overcome bullets with higher BCs and better accuracy at the same time.
