This is the second time Ive taken out my Bushy and cant believe the accuracy im getting out of it. The rifle is the "M4" style and it is more accurate than the 20in bbl I used to own. At 100 yds I can keep a magazine in the head of a sihlloute (spelling) target standing. To me thats awesome, thats 30rnds in that area with iron sights. Im using the adcom ammo and have had no problems with it so far. (heard this ammo has some issues) I use to shoot a .308 and that was accurate. Really didnt think id get this kind of accuracy out of a used ar. ETA When I say inside the head of the target im talking tight groups in that area. Not scattered all over. Austin |

I have 3 Bushmasters and I agree, their barrels are fantastic. My Bushmaster 20" V-Match is simply a basic HBAR with a free float tube. Shooting it with Winchester White Box 45gr JHP ammo I get 1" @ 100 yards for 5 shot groups. That doesn't suck. Bill ETA: The V-Match is a flat top without iron sights. My V-Match has a 3.3-10x44 scope on it. |
| I have Bushmaster barrels on my mutt guns. The 24" HBAR shoots great - I can get 4"-5" 10-15 shot groups at 100 yd using WOLF ammo (minute of head). However, my Bushmaster 16" M4 shoots groups about twice the size of the 24" HBAR... I can't figure out why, but overall the 16" M4 isn't giving me the results I want (using the same ammo and optics as the 24" HBAR). |
I agree. Some people don't like the 1/9 twist and demand 1/7 (Bushmaster does offer 1/7 twist for certain barrels). I just know that Bushmaster offers the most variety in 4150 steel with chrome lined bores and chambers (5.56N) with threaded muzzles for well under the asking price of its competitors. |
| Well, I've must have got a bad barrel or it really doesn't like cheap WWB or Blackhills too much. My 14.5" M4 averages 3"-4" groups @ 100 yards. I've put a better trigger on it, but if that doesn't help I'll try those Tubb's Final Finish bullets on it too see if that tightens up its groups. |
Bushie makes nice barrels. (better than I can shoot). But NOVEKE makes works of art. Those are VERY accurite. In 1/9 cant falt them. I Consider bushmaster to be a Ok AR mfg.(when not rushed) Some qulity problems. But in 1/7 I would go Colt, LMT or CMMG. I would go bushie over RRA unless its SS. Then both are the same. No problems with there barrels. I wish they offered real M4 feed ramps and 1/7 std. And do better testing before they release new products onto the market that just dont work. M17 imbus,BAR10 and Carbon type guns.

I agree 100% with that. They need to go back to what go them where they are, quality AR's. TS |
I agree as well. Real M4 feed ramps, 1/7 twist, and F FSB's would be nice. |
At 100 yd, I was using a 8-32x scope (at 8x-10x) on my 24" AR15. I made the mistake of using 8.5x11 paper targets at 100 yd and I can barely see my bullseyes with iron sights. At 50 yd and 25 yd, I use iron sights. I can clearly see a difference in precision between the 16" M4 and 24" AR15. The 24" shoots much tighter groups consistently and the 16" will group approximately 2-3 times that of the 24" groupings. I even switched to a Samson MRFS-C FFHG on the M4 and got the same groups. However, I still had the front handguard retainer on the barrel at the time. I figure that may have screwed with the barrel harmonics. I always take the front sling + swivel off the Bushmaster barrels since I don't use them, and they are loose objects attached to the barrel. |
| It has been my experience that bushmaster barrels produced 2-3 years ago are much better than the ones currently produced. The older ones could shoot sub-moa with standard 55 gr. and match ammo all the way up to 75 gr. With the current ones, 2-3 inches up to 4-5 inches are the norm. As a result of this, I switched. The are many good barrel makers out there, don't confine yourself to bushmaster. |
Can anyone else confirm this? My 16" M4 was purchased early 2006. The 24" HBAR was purchased late 2004 and was probably manufactured well before then (not in high demand, probably very old stock). |
| I built and A3 last year using a CMT upper, a Bushmaster 20’ HBAR and Jewel trigger group. The load I use for this AR is 22.1gn of N133, 69gn Sierra HPBT. It is a very accurate firearm. Several of the members of my gun club have let me try there Bushmasters. And the one thing I would recommend is to get Bushmasters two stage competition trigger group or a Jewel trigger group. The standard trigger group is good but not great |
I reciently built another AR (all Bushmaster) with a Bushmaster 16" HBAR and it is another great shooter. I don't see any difference in it and the ones much older. BTW, I do have a Service Rifle with a Kreiger barrel that is from another planet, but for chrome lined accuracy, I have little to complain about the Bushmaster's and they are made of the correct steel, 4150. Good Luck Bill |
can't confirm anything , but my 16" M4 is not very accurate. mine is capable but no sub-moa. My 20" SP1 is heads and tails above. But i think the big difference most of the time is the sight radius between the two. The full lenbth make a big difference. You can't compare without considering this |
| This thread really caught my eye because I shot my XM15-E2S this last weekend with a new TA31RCO-M4. At 50m it was pretty much a tack driver but out at 100m it was a disappointment. 3"-4" 5 shot groups was the norm. Many times the shots were +/- MOA but there was always the flyer that screwed up the group. I was shooting Radway Green but switched to WWB with little improvment. Contemplating the next step... |
I used magnified optics and still got the same results at 25 yd and 50 yd. |
