7.5 inch AR-15 reliability

[BWT]

I had a 7.5" SBR for several years. It was extremely reliable but pretty violent in terms of recoil.

Thank you for your observation.

What make was it?

What kind of ammo could you run it?

What malfunctions (if any) did you experience?

What buffer weight did you use?

Was it a standard GI Spring?

Did it take time to get it running or was it good to go out the gate?

I sincerely appreciate it,

Brandon.

ETA: What muzzle device did you have mounted?

What kind of BCG did you use?

Did it require extra lube in comparison to others?

Sorry for the brevity. I was on my phone and had to run.

Spent part of the day shooting a buddy of mines 7.5" Adams Arms upper. The thing I can say without hesitation was that it was a helluva lot of fun to shoot!!! I did not find the blast to be anymore obnoxious then a 10.3" MK18. Shots on steel at ~75 meters all day long. I personally think this would make a great "truck gun". One has to remember its intended purpose. 100 meters and closer I think this would be a very nice concealable option. It belongs to a good friend of mine who is an active duty 3rd Group guy. He helped sell me on it. I had a huge grin the entire time.

Just my two cents.
