With fall in full swing for many components of the nation, it’s time to see a few of the initiatives we had on a regular basis on this planet to work on. Whereas some first-time consumers have been working to gun shops to buy a handgun or rifle for defense, extra seasoned gun house owners have been accumulating components to construct out their dream rifles or pistols. Whereas I noticed plenty of issues out of inventory at one level or one other, sure components like lowers and Brownells BRN-180 uppers have been all the time prepared for the buyer throughout these attempting occasions. With that, right here is the breakdown of my BRN-180s Pistol construct!
Brownells BRN-180s
Should you aren’t accustomed to the BRN-180 line, you’ll be able to learn some evaluations right here at AmmoLand. Brownells has delivered an incredible choice for AR-15 house owners with this line of full uppers in numerous lengths: 10”, 16”, and 18”. Any BRN-180 higher will match any Mil-spec decrease and permits the consumer a fairly priced piston higher. The piston higher has some benefits over a Direct Impingement gun, one of the crucial apparent is that it doesn’t require a buffer system. The shortage of a buff permits for a folding pistol brace or inventory should you select a rifle-length higher.
The BRN-180 is a contemporary recreation of the AR-180 that was developed by Eugene Stoner, so in essence, this platform shares fairly a little bit of historical past and components with the AR-15. For the typical gun proprietor, this implies you could take any outdated pistol decrease or rifle decrease and throw on the suitable size higher as you see match!
For my pistol, I made a decision to make use of an Aero Precision M4E1 decrease, considered one of my favorites to construct with. The Aero decrease has loads of enhancements to your normal AR-lower, first amongst them the built-in set off guard and the set screw for the bolt catch. These little upgrades make constructing this decrease a lot simpler than a regular decrease, and I’ve all the time discovered them moderately priced with very high-quality machining to match. Throughout the darkest weeks of quarantine, I by no means noticed these decrease receivers out of inventory on Brownells.
The Aero Precision decrease components kits have been a special story, in reality I ended up ordering two kits from two totally different retailers: Optics Planet and Brownells. After I ordered from Optics Planet, it was as a result of the components kits have been out of inventory at Brownells, however then I ended up getting antsy, and it took over per week to get a transport affirmation from Optics Planet. In that point the decrease components kits have been again in inventory at Brownells so I bought one other from there, ultimately I had two components kits, which is rarely a nasty factor!
At this level, I had just about every part I wanted to construct a decrease aside from the brace I needed, for that I put in a name to my pals at Palmetto State Armory. In case you have adopted PSA by their journey of constructing AKs and the AKV you will have observed their collaboration with SB Tactical to ship the triangle folding brace to the market. That is by far my favourite brace out there at present, largely as a result of triangle folders look cooler than the rest out there! With the BRN-180 not requiring a buffer system, this meant the triangle folding brace could possibly be hooked up through a 1913 picatinny rail.
Brownells does have devoted BRN-180 lowers however they’ve been out of inventory and on pending pre-order for a while. I checked for per week with out discovering them earlier than I made a decision to go the usual AR-15 decrease route. Should you select to do as I did, the one half you will want is a pic adapter to interchange the buffer tube. KNS Precision provides that answer, and it is vitally straightforward to put in on any AR-lower. Be sure to choose the flanged model to carry the rear detent pin in place. I’d additionally suggest utilizing a contact of thread locker on the nut that holds the Picatinny rail to the buffer adapter.
With the decrease construct and the pistol brace secured, the final half to think about was an optic. I’ve pre-ordered the Main Arms 1x Cyclops Prismatic optic however within the meantime, I needed to have one thing to toss on the pistol in order that I might hit the vary. Main Arms has a plethora of choices to select from, together with a prismatic line-up, low variable optics just like the one I take advantage of for 3-Gun, increased magnification for long-range work, and an excellent pink dot choice. Whereas Main Arms is engaged on dropping some brand-new choices quickly, they have been sort sufficient to ship out their MD-ADS Pink Dot. The MD-ADS is an older model however nonetheless offers a crisp pink dot and a micro footprint for mounting options. After a fast vary session to sight in, I used to be very pleased with its efficiency to this point and didn’t discover any blinking underneath recoil.
With the MD-ADS you’ll have to purchase a mounting choice because it doesn’t ship with one apart from the direct picatinny mount. That is too low to be used with AR-style uppers, however the answer is easy sufficient as there are a variety of mounts that match the micro footprint. For my selection, I appeared for a Scalarworks decrease 1/third however had no luck find them in inventory anyplace. As a backup, I went with the Geissele Tremendous Precision decrease 1/third micro mount, which labored completely with the optic.
The final piece I added to this pistol was an upgraded set off, mil-spec is okay, however I a lot favor a single-stage set off. Palmetto State Armory has lately launched their line of triggers they usually requested me to check out them, it was actually good luck and likelihood that it was right here in time for this construct! My favourite half about putting in the set off is that it’s self-contained and arrives assembled. All it is advisable do is about it into the receiver, drop within the pins to carry it in place, and tighten down on two set screws contained in the set off housing to safe the pins tightly in place. If you’re accustomed to Timney triggers, it is a very comparable setup. The only-stage set off has a curved face and pulls round 3.5 lbs. That is my favourite sort of set off, and Palmetto has delivered a winner with the worth level. Time will inform how the set screws do at staying safe, however to this point, it has labored with out situation.
After a fast vary journey to check match and performance, every part with the BRN-180s higher and the assembled pistol decrease checked out. Why construct a BRN-180 pistol? We’ll revisit that in full after I get a day on the vary. at present, I’m ready for the devoted BRN-180 decrease to point out up. When it does, we’ll go into depth in regards to the variations between a regular AR decrease construct and the devoted decrease. I did have the prospect to shoot the pistol at 50 yards to sight within the pink dot, and it solely took ten rounds to get my group and 0.
