This is my latest personal build AR.
After contemplating several alternatives I decided the Canadians may have something right with their M16 trends and decided to incorporate some of those ideas into an all around rifle.
I hope it may give some potential builders good ideas to formulate a rifle upon.

I started with a Double Star stripped lower and an Evolution Gun Works stripped flat top upper.
The Barrel is a Government profile chrome lined 20" Bushmaster 1-9 twist.
I won't use bullets heavier than 68 grains in this rifle, choose a 1-7 twist if you think you will.
I can live with rail forends and this set up is from Midwest Industries.
It isn't free floated, it was hand fitted to selected parts and doesn't need to be.
It is tight enough that chucking the rifle in a vise and trying to rotate the forend doesn't work.
I like this set up and it is very adaptable.
I own a couple Vers Pod bipods so I added a rail pod mount 'just in case'.
The Bolt and Carrier are from Smith Enterprise and the small parts come from a Government supplier.
Charging handle is a standard USGI with a Badger Ordinance second generation "Tac-Latch".
The front and rear sights are Tritium on a DPMS carry handle.
The Flash hider is a Yankee Hill Phantom ll
This hider/brake is effective and the crennelations make it an effective strike weapon, no bayonet needed.

What the Canadians did to influence me was to adapt the rifle for complete ambidextrious control and suitability for people of all statures.
As such the lower is mated to a six position collapsing stock assembly.
A Midwest Industry single point sling attachment is added at the receiver and the sling can be attached to either side.
Trigger assembly is a Rock River two stage, I like these if you like somethig else then by all means use it.
The selector is an ambidextrious version from DPMS and the magazine catch is an ambidextrious Norgon Enterprise.

The pistol grip is a rigid ambidextrious ErgoGrip, the more I use these on rifles the more I like them but I always have liked the grip on the H&K G3 and this is what these are based upon.
The rest of the small parts are Goverment issue.
I believe a rifle built along these trends will be suitable for the majority of users.
It will fit, it is adapatable to a wide range of uses and it is more than sufficiently accurate for the majority of shooting.
I hope this helps potential builders to decide exactly what they may need on their rifle without going overboard.

I should mention a little issue I had with the Bushmaster barrel assembly.

The forged front sight base they are so fond of mentioning in there advertisement is not the taller F marked version for use with flat tops and I am not sure you can even special order an F marked front sight base from Bushmaster.
I have asked when ordering and the only answer I ever received was "We'll look into it. Do you still want the barrels if they can't be had?"

On the plus side, the front sight tower is taper pin installed and properly indexed, checked with a straight edge on a levelled table.

The front sight tower sight protecting ears were out of specification on this barrel also.
Too thick and squashed too close to the front sight portal, they would not allow a sight wrench to pass down to the front sight.
Indeed, it appears the manufacturer was aware of this and instead of clearancing the sight ears, the manufacturer, or assembler, used a drill bit to enlarge the clearance at the sight portal so a sight could be dropped in and installed with a pin punch.

The front sight assembly was frosted in the portal because no lubricant was used in the assembly and extremely difficult to remove.
It was so frozen that upon receipt it could not even be moved for sight adjustment.
I had to soak for 48 hours in a penetrating oil before the sight assembly would move.
After removal, clearancing the sight ears, cleaning and lubricating, the Meprolight tritium front sight installed without issue. Since it is also slightly taller, it cowitnessed with the flat top carry handle sight assembly and I was able to achieve a proper zero.
It also works fine with a Midwest Industry BUIS.

These are minor issues but I think builders should be aware of this.
