Brownells, largely, began the retro resurgence of the previous couple of years. Whereas they did get out of the sport with full weapons, they nonetheless provide elements and uppers. The latest batch of uppers is extra trendy and consists of the Brownells 733, a Mannequin 733 clone. Sure, the 733 everyone knows and love from the film Warmth. When Brownells supplied me a assessment of this higher, I promptly despatched them my delivery information and I began loading magazines.
Brownells @ TFB:
Disclosures are essential in any assessment so the viewers has all of the details. Brownells reached out to me and supplied to provide me the higher. Being a fan of carry handles usually and the film Warmth specifically, I mentioned sure to that provide. I paid for the ammo.

Design
The 733 higher is constructed round a C7 receiver. That may be a variant of the A1, but it surely provides the newer A2-style brass deflector. The rear sight continues to be a normal A1 mannequin with two apertures within the rear sight. The long-range aperture is marked with an “L” as could be anticipated.
Identical to the unique 733, the Brownells model has a light-weight, chrome-lined 11.5-inch barrel. This one is made by Luth-AR. In step with the A1 theme, the flash hider is an A1-style birdcage with slots across the whole circumference. That is completely different than the way more frequent A2 flash hider, which has a closed underside to cut back the quantity of mud it kicks up.
One level to notice is that the Brownells 733 higher doesn’t have M4 feed ramps. These are normal lately as a result of they do assist with reliability, however they might not be “clone right” on this gun. One other throwback characteristic is the teardrop ahead help. It features simply the identical as a daily spherical ahead help however has extra floor space.

No M-4 feed ramps right here, but it surely nonetheless runs high-quality with all sorts of ammo examined.
On The Vary
I broke within the 733 higher in the one method that appeared acceptable: on a post-sample machinegun decrease. It’s what Neil McCauley would have wished. I put about 150 rounds via it within the first outing, starting from 55-grain manufacturing facility ammo to 77-grain reloads. My dad occurred by the capturing vary whereas I used to be capturing full-auto, and he took a flip. This setup put the largest smile I’ve seen on his face in a very long time.
I had a lot enjoyable capturing it as an identical gun that I did various it. For probably the most half, it was simply good, uneventful enjoyable. The one warning signal got here after I dumped a stable 60-round burst from an ATI/Schmeisser quad stack journal. The gun was already heat after I began, and after that prolonged run on the cyclic charge, the fuel tube was glowing purple. When it lastly cooled off it had some apparent heat-related coloration modifications, but it surely continued to perform simply high-quality.

As soon as the fuel tube cooled off it turned a purple/blue coloration gradient.
The dearth of M4 feed ramps was not a problem in any respect, no matter ammo. I used the whole lot from low cost .223 Remington FMJ ammo as much as 77-grain boat tail hole factors and the whole lot ran and not using a hitch. Feeding was additionally flawless throughout a variety of magazines together with Duramag, Magpul, Amend2, Hera Arms, FAB Protection, and Okay Surefeed fashions.

Carry deal with uppers aren’t all the time one of the best hosts for optics, however I attempted a number of optics on the mounting gap. I used my trusty outdated Trijicon reflex sight and the Major Arms 3x Micro Prism at varied instances. Each labored properly, however the vibes from the Trijicon had been unmatched.

One other accent I used was the SilencerCo Omega 300 mounted with the Griffin Armament A2 mount. Although it says A2 within the title, it additionally labored with the A1 flash hider on this higher. It functioned high-quality however ran nearly how you’ll count on any brief barrel direct impingement 5.56 to run so far as again stress.
Velocity Testing
Brief barrels commerce velocity for maneuverability. However simply how a lot do they lose? That varies lots relying on simply how brief it’s and what ammunition is used. I attempted a bunch of hundreds and gathered velocity information with my Garmin Xero C1 chronograph.
Winchester M193 55-grain 5.56 NATO: 2,806 FPS
PMC 55-grain .223 Rem: 2,546 FPS
Handloaded 77-grain Match Ammo: 2,324 FPS
These numbers hand over a number of hundred FPS to the longer weapons, however the 733 completely has the sting in maneuverability and weight.
The Garmin Xero C1 chronograph is unmatched for ease of use.

Conclusion
With a $699 price ticket, the Brownells 733 higher just isn’t low cost. However it does embrace options like a chrome-lined barrel and a lifetime Brownells guarantee that assist justify the worth. It additionally performs properly with a wide range of ammo and has unmatched Nineteen Eighties and Nineties crime film vibes. I imply, simply take a look at this image of Lt. Castillo from the seminal TV present Miami Vice:

If that doesn’t make you need one, I don’t know what’s going to. The Brownells 733 is an superior choice if you’d like an iconic AR pistol or SBR. It’s not the proper selection if you wish to mount IR lasers, however it’s an instance of how mild and nimble a standard shorty AR15 could be. Whereas trendy uppers could outclass it in some regards, it’s completely unmatched within the enjoyable division.
