I bought 50 AR-10 Magpuls for a high price, but not parting with any. I’m happy.
Back around 89, I was buying case after case of Q3131 white box for $179/thou; wifey was sure I had went off the deep end.
Haven’t bought any .556 since; haven’t run out, heck my grandkids won’t run out either. Same with 22LR, haven’t bought any since early 90’s and never will the rest of my days. That’s a secure feelin ya know. Same with mags, but I tell ya those Scar mags are sure spendy & rare too.
