THIS IS PART I. BELOW THERE'S A LINK TO PART II.

The AR-15. America's rifle.

I've played with my share of fine ARs - LWRC, Noveske, Armalite,
BCM, LaRue, LMT... and also with quality mainstream brands like
DPMS, Rock River, Smith&Wesson, Stag Arms, Colts and Bushys.

The thing about ARs is that you can't place a level of expectation
from each rifle based on the relation to its price. Some pricier
ones stand out, while others seemed only fair. Same goes for
lesser expensive ARs.

With this in mind, you CAN create an equally formidable AR15 from
a value standpoint without needing to fall victim to the idea that
a $4000 LWRC is the only thing that will make you happy because
you spent so much - expecting more. The modularity of this rifle
allows us to build virtually whatever we want.

With research... I set out to find a good start. Something that
has the makings of an exceptional AR. Giving you something more
than you expected. Something that breaks the mould. Something
inexpensive with a lot of value from the start.

What I found was the Smith & Wesson MP-15 Sport.

A few of you might've already purchase this rifle for its entry level
price point... but not knowing the specifics of what you were buying.
Getting much more value for your money.

Smith & Wesson change the game for entry level ARs by giving you
more and taking away old Milspec components. The M&P Sport is
without a forward assist, a dust cover and you cannot change the
trigger guard. Keeping an open mind you can easily realize that
these features have only been around for this long because of
Milspec demands. Cutting back on weight & costs, Smith & Wesson
took the leap... and I'm glad they did.

The original rifle - Smith & Wesson MP-15 Sport. "Plain Jane"
as it may appear, has the necessary ingredients of a star player
in the AR15 market with its exceptional barrel. Let's see what
happens to this new comer when left on my bench for weekend.



Reborn from a day's work... a STAR is born. More tactical,
better components, more accurate... completely functional in
all aspects. "Plain Jane" meets sexy.



I went with a Dark Earth mixture for this reborn AR15. Not that
it's functional in any way. Mainly for an attractive appearance
creating the "double take" factor from onlookers.



From behind she sits proud, showing off her hot, yet functional,
features. I will get into her private parts below...




The unique aspect of what makes this factory AR15 a definite
"buy" from my perspective is the Melonite treated target bull
barrel - a 1:8" twist utilizing the 5R rifling. Treated inside and
out, what's unique about this barrel is that the bull configuration
remains consistent even under the handguard, unlike most "pencil
thin" AR barrels.

A thicker barrel is always better - for heat dissipation & improved
barrel harmonics producing better accuracy. Obviously not needed
for sportier hunting applications.

Melonite is the same thing as Tenifer... only difference is that
"Melonite" is a trademarked name. Without getting too complicated,
the process is known as ferritic nitrocarburizing which improves
scuffing resistance, fatigue properties and corrosion resistance.
It is not a coating, it is a "gaseous, salt nitriding bath, ion or
plasma, or fluidized-bed". It occurs at temperatures at around
1,050 degrees.

Is it better than Chromed Lined? Yes. It is a process that changes
the metallic properties of steel, not simply coat it. Chrome lined
barrels have a bonded layer of a harder & denser materials known
as Chromium and Molybdenum. Although Chrome-Lined has long
been a standard improvement for metals around the world, Melonite
is still over 80% more corrosion resistant and 99% salt-water
corrosion resistant.

Most ARs are designed with a 1:9" twists that works fine to
stabilize most lighter rounds that start with 55gr to 69gr.

This rifle's 1:8" twist allows you to use heavier bullets which is
stabilized by the faster spin. 5R rifling produces less damage
to the bullets jacket giving you better consistency. This rifling
is also known for better sealing of gases to produce higher
velocities. 5R is also easier to clean producing less fouling.

Shooting heavier pills tend to be more accurate because they
are less effected by environmental factors.

This barrel will NOT like light factory ammo so don't waste your
money. The twist and rifling here only prefers heavier bullets -
mainly 75gr & 77gr.



Pushing back the Delta Ring, it is easy to remove the 7" two
piece plastic handguard. I now have clearance to remove the
A2 front site gas block which will not work with the new free
floating quad-rail.

You may have seen many videos online or people telling you
that removing factory installed A2 front site is simple, that by
tapping out the 2 pins with a punch set is all you'll need - NOT
with this rifle. The pins are virtually immobile! I ruined a
quality punch in efforts to remove them, it was like it was built
not to be modified. I don't know if it was just my rifle but none-
theless, I am determined.

I used my Dremel inserting the slim metal cutter to easily cut
and dislodge the A2 front site gas block. Making very small
scratches on the barrel, you will notice that the pins are still in
place. Now with more leverage to remove the pins, they STILL
won't budge. I had to cleanly cut them out as well.



I installed a new high quality Midwest Industries threaded barrel
nut, a new Yankee Hill low profile gas block and an all aluminum
FREE FLOATING 10" quad-rail where the upper rail is extended over
the barrel nut for a "no-gap" monolithic look with the upper receiver.

Tapco rail covers on each side for a smooth, non-sharp rail
feeling.



To finish off the look, I've also installed a Midwest Industries
black handguard cap at the inner front end of my quad-rail.

Topped the rail off with a Troy Industries all steel folding
battle front site for the times I'm not using optics.



My favorite AR15 accessory - the custom "Ghost" muzzle
brake that needs no threading. Solid steel, precision
mill work... completely effective in eliminating whatever
recoil that may knock off your Ray Bans. Work of art.

Intelligently designed for full inner capture of muzzle
gases and redirecting them upwards and sideways for no
muzzle jump. This muzzle brake can also be milled for
threaded barrels too - inquire with me for more info.



Fit and finish between upper and lower is very tight,
without any play. The lower is quality forged aluminum.

While researching for optics... I focused on a few factors:

1. Quality built without needing to spend hundreds.
2. Super short, super light, yet giving me full optics capability.
3. Strongest magnification in this short and light profile.
4. Long eye relief. 3" is not cutting it. I need 4-5" eye relief
for comfortable shooting while standing and moving.

My result... the BSA Contender 6-24x40mm IR Mil-dot.

At a mere 17 ounces at only 14" long with a 4-5" eye relief
offering 6-24x magnification with clear optics for under
$250... a no brainer for me, a "must" buy for my semis.

1/8th adjustments, locking turrets and illuminated mil-dot
reticle just makes this scope a default for all my AR15's.

has more than 9 images at the moment. Read Part II of this
thread to learn more about this AR15 project.)

Terrific! BTW, thanks for the info on "Melonite." I'd heard a bit about it, but learned much more here.

Benny you got something against handguns? You should do a handgun project.
No, nothing against handguns. They have their place.
Whether you like small for CCW, larger for accuracy &
comfortability... it's the same story all the time. You buy
a few, you keep a few you like, not much else to say.

Living in NY keeps you in check from getting something
nice that is great for practice and repeatability like a Kel
Tec PMR-30. That would be fun to shoot & write about.

My mainstay is the Glock 30, large enough for comfort
in my hands and shooting, but small enough for CCW.
And it's very accurate in it's class. Plus, I prefer .45ACP
over 9mm, 40S&W, etc. Whereas, in rifles, I enjoy all
the calibers, they all are very different.

Nothing against guns, they just don't offer as much
science and things to talk about like rifles.

Peace,
GH-07

Is that the "Ghost Muzzle" you had input on and or designed with Grizzly GW?
I may be interested in a threaded one for my LMT barrel I've been waiting 2 months for!

Ghost, really nicely thought out been thinking about the FDE free float but if I pin I'm stuck with it .not really but you know!
I went with a T10 from MI with the end cap the guy I get my rails from adds the trim ring to all his YHM andMI rails and he is still cheaper than anyone so far. But that stock I love it awesome cheek rest .i bought the Magpul ACS thinking yes but it was no . How does the color match to the other FDE things?

I haven't compared Troy products in colors so I can't really
say. But from my experience most product manufacturers
stay fairly close when it comes to Dark Earth, not so much
with Olive Drab.

Pinning is only for the buttstock to stop collapsibility, the
free float rails come off whenever you want.

got new S&W Sport right before the mess at Newtown. The price was only $649 delivered to my FFL. Best bang for the buck in AR's as far as Im concerned. The 5R melonite barrel is sweet and I don't miss the dust cover/ forward assist one bit. Since shooting M16's/AR15's in the early 80's till now Ive never needed a F/A nor has anyone I shot with. The dust cover isn't needed for my purposes as I don't crawl around the Mekong Delta mud and don't see sand storms either. S&W has in the last couple months done away with the 5R rifling(assuming due to cost). I put magpul carbine front grips, Ace entry stock, MS3 sling and an Aimpoint Pro on it and that's it. Its currently my favorite go to shooter in my safe.

is your scope mount backwards?
If you want to look at it that way, then it is. Does it make
a difference in accuracy, proper shooting, etc... of course
not... then what's the point? :)

It was mounted that way for my personal reasons:
1) better weight balance
2) scope goes further back
3) quick thumb forward release instead of backwards.

I have the same mount and in the same direction. I had to get it as far back as possible and allow for my flip up sites.
Works just fine for me in my set up.

It was actually this post that gave me the idea!
Thanks GH!
