They push the boundaries of manufacturing and challenge the status quo by constantly looking for new ways to develop and evolve.

Caliber Marking 5.The AR has undergone many stages and several iterations in its over half a century, long active life. Besides satisfaction as the primary benefit of building an AR, there are few other benefits of assembling two halves into one functional unit.

It may be an arguable statement, but the most important things that an average AR builder wants from his lower receiver are the good fit, ergonomics, and finish.

If we neglect cast lowers as parts of doubtful value and futuristic polymer receivers of limited durability than we have to choose traditional materials and technological processes. Some gun owners also pay great attention to aesthetics and finish. They don't want any blemishes or defects on their lower receiver and they choose one that perfectly matches their upper receiver and the rest of the gun.

As mentioned in the previous section, the lowers come in various types with their own strengths and weaknesses that you should weigh. Though it may present a challenge for an average AR owner, for this guide, we have selected mainly stripped lower receivers except one.

As a hunk of metal with holes in it, a stripped AR lower does allow you to pick and choose better ambidexterity controls, built in trigger guards, "skulls and anything off of stock". As you probably know, the original AR platform has changed through the years and these improvements are marked as the different types of AR's. You'll often hear people refer to A1, A2, A3, or A4, but it means they are actually related to the different generations of the M16 rifle.

Historical reenactments and the increased interest of collectors for Vietnam War spawned offerings of the early AR and M16A1 rifles as well as the parts kits for builders. These lower receivers are immediately recognizable by the "Full Magazine Fence" typical for the third iteration in the A1 lower series.

The Brownells machined them to mil-spec dimensions and finished with a matte grey or black hard anodized finish to match most of the modern uppers found on the market today. Some people also remark that the anodizing isn't perfect as you might even come across occasional traces of residue that slightly discolor the anodizing process. Despite sporadic complaints, NoDak Spud products are on the high end of quality and they have maybe the best reproduction lowers on the market that match the features of the original M16A1 receiver.

Additionally, this lower fits all standard AR components of upper receivers without issue. Since the "retro AR" scene had exploded in the last few years, many AR manufacturers, dealers and merchants have found a niche in this market. The forged lowers from NDS are later machined by Brownells to become the correct lower for replicas of early U.

This second type lower also known as the "Partial Fence" type receiver has, unlike the first "Slabside" type, the captive pivot pins, which were held in place by a detent housed on the added reinforcement rib. This "partial fence" reinforcement is placed above the magazine release and just below the ejection port cover. In the early stages, Brownells had a problem with one commitment segment of the AR community who preferred the original Colt XM grey finish.

The Brownells receivers were excellent but too black. However, currently, they provide receivers with both grey and black hardcoat anodized finish for building reproductions of the original XM16E1. In fact, they feature only aesthetic issues due to the failure in the anodizing process. The blemish units may come in varying finishes ranging from shiny green to dark grey. This easily recognizable receiver replicates the exact contours of that "Partial Magazine Fence" configuration and offers the perfect unit for a Retro build of the first M16 rifles issued to the troops in Vietnam.

Since its founding, Brownells has been a parts company, but from they started introducing their first line of firearms. The M16A1 upper and lower receivers are built from forged T6 aluminum at NoDak mill shop and then precision-machined to final dimensions by Brownells.

The Brownells blemished stripped lowers under manufacturer number WB are also often cheaper than regular ones because of small aesthetics imperfections such as discoloration and some anodizing flaws. Although the manufacturer claims that each of their blemished M16 A1 lower receivers meets all the requirements and replicates the exact contours of the M16A1 receiver, during assembling you can expect more than the usual amount of wiggle between the two receivers, especially when pairing a lower and upper of different provenience.

Because of anodizing blemishes the finish on these lowers varies quite a bit, ranging from greenish tinted black to dull, dark grey. The Spikes Tactical is the renowned manufacturer of complete firearms, but also they offer stripped and assembled AR receivers' models. Whereas most stock triggers are bad, this one is a better than average trigger. Besides that this lower set includes a Spikes Tactical Pro Pistol grip, an M4 style six-position stock on a mil-spec buffer tube 1. The M4-style adjustable buttstock and standard black pistol grip are molded from reinforced polymer to help reduce the weight, but this basic furniture isn't that great, and most AR owners change them out anyway.Nobody in the industry matches our quality and attention to detail.

In order to help you decide what "Retro" model you want to build, and what lower and upper receiver is appropriate, please go to www. Due to the difficulty in transforming "A2" forgings into "Retro" lowers, we have invested in several dedicated "Retro" style forging tools. This required substantial time and money to tool up for, but in the end, was well worth the effort.

We know you will be very pleased with the finished products. This is next to impossible given all the variables that are involved. One of the biggest problems is the age and use of your surplus upper. If you need them to match perfectly we recommend that you order yours "in the white".

I parkerized both firearms, and I had the upper and lower receiver color matched. They came out really well, in fact excellent.

Their is three different types of lower receivers that were made, so it's important to be able to match it correctly to the rest of the firearm. The upper receiver had two ones that were mostly used, one without the deflector 's and one with the deflector. The much older ones did not have a bolt assist on them early 's. The retrofit M16A1 lower receiver is awesome, it is a well made product.
