New Armalite M15-A2

I just picked up an Armalite M15-A2 from my local gun store. It's my first AR and it is a beauty, used, but I can't see any evidence that it was ever shot. Really. There are no wear marks on the bolt face or bolt carrier, in fact the entire gun seems to be in perfect condition.

The store owner gave me a very good price of $895 (out the door), including two 30 round magazines.

The M15-A2 is stock-as-a-rock. Chrome lined, double lapped, cold forged 4150 steel barrel, 2 stage trigger, two aperture A2 rear sight, high contrast front sight.

Upon making my final payment, the shop owner installed a 22LR conversion kit, gave me a box of 22LR and gave me a lesson on zeroing in the rifle. I couldn't believe how a little 22 round could cycle the action with no malfunctions, and how accurate the Armalite is. Nickle size groups at 25 yards.

Saturday, I'm going to an 300 yard range and putting some 5.56 rounds through it. I'll give a range report. The gun shop owner said to zero the gun at 1.7 inches high at 50 yards, and it should be capable of hitting a 10" target out to 300 yards and spot on at 200 yards. He said this would take advantage of the 5.56's flat trajectory.

So how did I do? Any suggestions or comments about the Armalite M15-A2, good or bad are welcome.

If you use military ball ammunition try zeroing in at 25 meters.

I've had great success with this in the past with an M16

Edit: the bullet is still rising after the 25 meter mark but will fall to the same point at 300 meters. I've always been in the black with this.

Thanks, Joe. It's great to hear from an experienced marksman. The ballistics chart is very good.

It will be interesting to see just how the 25 yard, 22LR zero at the gun shop range will correlate with the "real deal" M193 rounds. Anyway, at least I'll have a starting point!

Congrats on the purchase. Was that $895 with the .22 kit?
The .22 conversion kit is a great addition. Saves a lot of money any pays for it self in short order!
Just to clarify though, the .22 kit has it's "own" action....much less recoil is required to operate it. My CMMG kit seems to fire anything I run through it, which is nice.
I used that sight in method as well. great advice.
Good luck with it and enjoy!

Oh, I meant to add...PICTURES PLEASE!

I didn't know the 22LR conversion bolt worked differently! That's why I was surprised the 22 would cycle the AR. Thanks for the information. So much to learn. The conversion bolt was loaned to me so we could shoot the M15-A2 at the shop's indoor (25 yard) range. I'm not sure who manufactured it but the gun shop owner quoted me a $225 price to buy one.

You are correct in that it would pay for its self in very short order. Also, there are a bunch of pesky armadillos around here that need a lesson in manners. My shotguns and pistols have too much report to use at 2:00AM.

I hope to post some pictures taken at the range on Saturday.

Thanks,

One Eye Jack

Actually the bullet is falling (ever so incrementally)... after if leaves the barrel....it's impossible for a bullet to rise.....But, if you meant to say that because of the upward angle of the barrel in relation to the target, that it is at a higher trajectory at 25 yards....then your right!

Just busting your balls a little bit!!

You are absolutely correct.
The bullet does in fact fall when it leaves the barrel. Since we know almost exactly how it falls we can point our barrels up and use the bullets trajectory to our advantage. In the bullets trajectory it is at the same height at two different points along its travel. I was lazy and wanted to skip all this and get to the good part.

1. Point the sights down, not barrel pointed up.
2. There are some instances where the trajectory does not lead to the bullet crossing the line of sight/plane of the sight twice.
