Summary of previous posts:
Between my son and I, have gone thru about 800rds out of a 1,000 rd case in my DPMS Classic A2 1x9 and his Oly PCR-4 1x9, all without issue. Good stuff, all rounds in good condition in the box, definite military power and quality at a good price.
1000+ mix of yrs mostly 80's but some small amt from the early 90's...not problems
Shot out of a BM w/ 20" 1:9 bbl.
I've shot many thousands of rounds of it, (best guess is 3000+), with no problems.
Fired out of both 16" HBAR, 16" M4, 20" HBAR (various makes)
no problems in RRA R-4 or Armalite 16 in
No problems here, mine was the 55 grain.
I also sold 1/2 my case to a friend who has match chambers and he had no problem with it either.
I've fired a bunch of it out (300+rnds) out of my bushcoltoly 16"SS/HBAR frankenrifle, and my J&T/DPMS 20"HBAR. Neither rifle is chrome lined and I have not had one ammo malfunction (with any ammo for that matter) Guess I'm just lucky.
P.S. this stuff will go through 1/4" mild steel plate at 100 yards from a 20" tube, and almost all the time from a 16" barrel.
Zero problems to report with:
20" Colt 6601 1/7 HBAR (two rifles)
16" Colt 6400C 1/7 M4
16" Colt 6920 upper 1/7 M4
16" Colt 6721 1/9 HBAR
16" LMT M4 upper 1/7 M4
16" RRA 1/9 HBAR
I'm just barely into my fourth 500rd case, but I have had zero issues in all of the above referenced weapons. The 6400C and 6920 upper have had the majority of M855 trigger time (over 1200 rounds between the two of them).
LE6920HB 1000 rds no problem
I have used 900,000rds of this ammo this year alone, and maybe had about 12-15k that is bad.[ split neck, bent rds, overpainting of the tips.] I link this ammo for use in M-249'S . this ammo is not military turn in's from the range. it comes directly from the LC ATK plant in MN . just remember that this ammo is factory seconds!! and they could do what they use to do before selling it to dealers. pull the heads, sell the powder, burn the brass and sell it as scrap. be very thankful that we can get this ammo. there is not more good deals on winchester Q3131A anymore. and remember when LC 5.56 SS109 was like gold about 2yrs ago [$300 for 1k if you can find it.] also there is a price increase coming june 1st from LC /ATK by 4% on there products. so stock up now.
