My AR-15 RECCE Build [Aero Precision Base]

If you are reading this, there is a good chance you have been afflicted with the constant need to build another AR.

It may have started off innocent enough, but now you are eating Ramen noodles, selling blood plasma, or like me, writing part-time to get your next fix.

I am an enabler.

I recommend leaning into it.

Don’t fight it. You won’t win.

The good news is that I can help with some suggestions, and that is what this article will be about.

If you are thinking about building your next jack of all trades RECCE Rifle, keep reading! I will go over my choices for my build and what I recommend!

Best Rifle in Its Class

The RECCE Rifle, pronounced “RECKY”, is one of the best working rifles for several situations.

Typically barrel length is 16”, but some people prefer an 18”. More people are using 13.7-14.5” barrels as well, but the 16” with a mid-length gas system typically gives the best compromise between velocity, maneuverability, and felt recoil.

Optics usually consist of a 1-6X low-powered variable optic (LPVO). You can go higher, or lower to a 1-4X depending on how far you plan to shoot targets.

A solid LPVO can make a RECCE Rifle shine with true 1X magnification which makes getting on target fast.

The best part about the RECCE Rifle is that you can make it your own. That is precisely why they are fun to build.

My Barrel

FN USA makes great barrels. I went with FN’s 16” CHF, Chrome-Lined, Mid-Length gassed barrel. This barrel is amazing quality. It is also more than accurate for a chrome-lined barrel.

The chrome-lining is double the thickness of typical government contract M4 carbine barrels and are the M249 SAW spec for lining.

For a semi-automatic AR15, this barrel will last and deal with heat very well. The MIL-B–11595E steel used is the same material used for their machine gun barrels.

I opted to pin my gas block myself for utmost reliability.

They are expensive compared to other brands, but you do honestly get what you pay for.

Accuracy is typically .75 MOA to 1.5 MOA depending on what loads I put down the pipe, but with its 1:7 twist rate, it is fond of Mk262 loads, and other 77 grain OTM loads from IMI, or Magtech.

My Bolt

My bolt carrier group (BCG) is a model sold by Brownells. For its price, it is one of the better BCGs on the market right now. They offer a budget-minded model, and a harder-use model which is the model I own.

My BCG is phosphated and chrome-lined internally in the carrier. The bolt is 158 Carpenter steel, but above all else, it is INDIVIDUALLY high-pressure tested (HPT), and magnetic particle inspected (MPI).

Most other companies only BATCH test their bolts which is why they are less expensive.

If you want to dive down what exactly that means, take a look at the Best Bolt Carrier Groups article we have!

After the HPT and MPI, the bolt is heat-treated and shot-peened. The gas key is properly staked and uses Grade 8 hardware per Colt TDP.

This BCG rocks and on occasion can be found for under $100 on sale. Keep an eye out and check the Daily Deals so you don’t miss sales.

The Receivers

Both upper and lower receivers are Aero Precision. They are the older, typical forged receivers made of T6 7075 aluminum.

For the price, Aero Precision is one of my favorite companies to use for receivers due to the quality and affordable pricing.

The fit between both the upper and the lower is good with little to no wobble. The tensioning screw wasn’t needed even though it came with one.

The lower parts kit that I used is a complete CMMG kit, and is one of my favorite kits for the price.

One of the best features with the CMMG kit is the standard mil-spec trigger that comes with. The trigger uses standard springs, and by no means is it match grade.

But the trigger is smooth, with no grit, and the reset is fantastic. I have used this trigger in multiple builds, and I can shoot sub-MOA with it, if the load and barrel can make it happen.

The Handguard

The handguard that I chose is the Daniel Defense MFR XS in a 15” with MLOK.

It has everything that you might expect from a handguard with its price range. It is very solid, robust, but also relatively lightweight. The MLOK pattern is at 3, 6, and 9 o’clock around the entire handguard.

Installation is one of the easier designs, and it doesn’t require timing the barrel nut for the gas tube. The locking mechanism is robust, and similar in design to the RIS system from previous designs.

Attached to the handguard is a Magpul MLOK hand-stop, which is comfortable for thumb-over-bore shooting.

The iron sights mounted are the basic Magpul polymer iron sights and at some point, will be upgraded to a more robust design.

At their price point, the basic Magpul iron sights are great, especially if they are last resort back-up irons. Luckily, the rear sight while folded will clear underneath my optic.

The Stock

The stock that I chose for this RECCE build was the Magpul UBR Gen2. This stock is built like a rock and is about as heavy as one.

Luckily, it does well in balancing my rifle out. I can not overstate how absolutely rock solid this design is.

I wanted something solid like an A2 rifle stock, but I also wanted adjustability if the need arose. That is why I made the decision to go with the UBR.

Once adjusted, there is ZERO wobble. The stock locks into place and is practically bomb-proof.

The buffer and spring are from VLTOR. It is their A5 system that uses an H2 weighted buffer. The spring is a standard rifle spring.

Along with a good muzzle brake, this system is superior to a typical carbine weighted and sized buffer and recoil spring. It really tames felt recoil, and keeps the weapon shooting flat.

The Optic

A RECCE Rifle is only as good as the optic that runs on it. I am a huge proponent of using an LPVO on a RECCE Rifle, and preferably of a rugged design that will last.

I chose the Trijicon 1-4x Accupower. It is a very solid middle of the road optic.

Its illumination is not as bright as a Vortex Razor 1-6x, but the reticle is a smart design. The circle dot reticle works well at close range or pushing out to moderate ranges of 400-500 yards.

Above all, the scope is rugged and can take a beating. This optic has yet to give me a hiccup.

An optic is only as good as the mount it resides in though. That is why I use my Trijicon in a BOBRO QD mount.

It is one of the more solid QD mounts, and quick-disconnect may or may not be important to you. It is for me and that is the only way to quickly get to back-up irons if an optic should die.

Parting Shots

RECCE Rifles can be done up in any sort of way. The great thing about them is that they are not like the Mk18 or Mk12.

It’s not a clone, and you can go ham on whatever parts you like. It is a versatile ideology of a rifle, and it’s hard to go wrong!
