First time poster and just set up an account.
Recently I purchased what was supposed to be a factory aero M5 18" rifle in 308. I was on a camping trip when I picked it up.
After a week I got the gun home and realized that the bolt is not locking back on the bolt catch. If is locking back on the magazine only.
I contacted the seller, private party, and he told me he had "Put the gun together with all factory Aero parts". So now he has listed the gun for sale as a new factory gun and I am hearing it is not that after I get the gun home and it's been a week.
Long story short, the guy threw an ar15 buffer and spring in it and it is binding. I happened to have a spare ar10 buffer from a previous ar10 project but now I need a spring.
Any suggestions on a go to sping for a carbine buffer set up on an 18" ar10?
Thanks and happy shooting.
