AR15 Question
v35
Member Posts: 12,710 ✭✭✭
I have a fellow who wants to trade an AR for another item I have and has given me the description below. He has two AR's for trade, but I really don't know what 6.8 SPC is, or stands for.
"I've got one in 6.8 SPC and one in 5.56/.223."
I already have an HBAR Colt, but would not mind having another to shoot, I just want to understand the difference.
EDIT:
I did a search on 6.8 in the forum. Disregard my inquiry.
EDIT II
Armalite,
Thanks for the description. Now, I need to decide if I should trade for the 6.8 or the 5.56. Since I akready have the 5.56 in the HBAR model, I may make the trade for the 6.8. Who knows, the ammo looks pricey and it may be just another "gimick" like the 45GAP. A round that may be harder to get as time goes on.
Thanks,
Aaron

With the hammer in the forward position, can the safety be switched from "fire" to "safe" on a standard semi auto AR15 with standard, unmodified trigger?
As it is the JP job will allow the switch, leading to a jam if you try to charge while in Safe position.
It's been some time since the JP installation and don't recall any issues but I'll have to dig in and see if that defect can be rectified by adjustment.
I don't know if it's a problem with other adjustable triggers.
P.S. The $50 Bushmaster lowers are nicely made & Sportsmans Guide has cheap DPMS lower parts kits.
I had exactly ONE fire control group which allowed re-cocking on safe and found that if the trigger was pulled while on safe, occasionally the hammer would fall when the safety was released. That FCG is in a bag labeled "UNSAFE" in my parts box.
I'll contact JP and see what they have to say.
The JP was adjusted to give a short 3.5# trigger pull with little overtravel.
Using a "speed hammer" & JP hammer spring it reliably fired hard Norinco primers but failed on 22lr in an USAF conversion kit.
A stock hammer spring brought it above 5#.
Before accepting a 5# pull, I'll retry using the JP hammer spring with a heavier mil spec hammer.
Should the Ar15 be able to cock with the safety in the "Safe" position?
Another way of putting the answer is that you can not engage the AR 15 safety to "on" with the hammer forward. I have seen AR safeties made that allow it to be engaged with the hammer forward and allow the hammer to be cocked with the safety engaged. I'm not sure of the purpose, don't recall the brand, but they were made that way by design, not defect.
