Will not work with the New Frontier Armory .45ACP bolt, as it has geometry that makes it incompatible with the feed angle of H&K USC pattern magazines.

MVB Industries AR-15 45ACP Magwell Adaptor is designed as a drop-in accessory for a standard AR-15 lower receiver and uses a standard H&K USC 45 caliber magazine.
There’s no need to go with a pistol-caliber specific AR lower on your next pistol-caliber carbine build. With the Stern Defense AR-15 9mm Conversion Adapter you have the ability to utilize popular pistol magazines which you may already have a supply of.
Stern Defense make two differ models of their Conversion Adapter, one which uses Glock® magazines, and one which uses either Smith & Wesson M&P or Sig 320/250 magazines.
The Stern Defense AR-15 9mm Conversion Adapter is easily installed into any mil-spec AR-15 lower receiver within seconds and even incorporates a last-round bolt hold open feature. Each adapter is machined from aluminum and requires the use of a 9mm/.40 S&W barrel and a Glock-cut bolt.
I could probably devote an entire website to Aero Precision’s various AR-15 combos, specials and one of a kinds. Anyhow, this time Aero Precision is combining their fantastic threaded M4E1 AR-15 upper receiver with their Atlas S-One handguard. The AERO PRECISION ATLAS S-ONE M4E1 AR-5 THREADED ASSEMBLED UPPER system is designed to match seamlessly creating an upper so sleek it rivals the rigidity and appearance of a monolithic upper. At $199 the system comes in cheaper than many quality handguards alone.
The ATLAS S-ONE is the newest addition to the Aero Precision Handguard lineup. Machined from 6061-T6 Aluminum, the S-ONE line of handguards are designed with size and weight in mind, providing the perfect handguard for your lightweight build. Our proprietary ATLAS attachment system is a durable and dependable mounting platform, maintaining a slim profile while still providing the strength and stability customers have grown to love from Aero Precision handguards.
Available in KeyMod™ and M-LOK® profiles with 12” and 15” options (7” and 9” options coming soon).
The M4E1 Threaded Assembled Upper Receiver features a new angular machined design that helps it stand apart from standard mil-spec upper receivers. This upper receiver features the same enhanced body profile as our M4E1 Enhanced Upper Receiver but is threaded to accept a standard AR15 barrel nut. It is forged from 7075-T6 Aluminum, precision machined to work with all mil-spec AR15 parts and includes the port door and forward assist pre-installed. Get the billet look without paying the billet price!
Note the current version of the PWS MOD 2 H3 Carbine Buffer features a fluted black body. The weight is also listed at 5.2 ounces versus 5.5 ounces of the original silver version pictured on this page.
The PWS MOD2 Carbine H3 Buffer is perfect for shooters who need to reduce cyclic rate or dampen recoil. The fluted design features minimal contact points within the buffer tube allowing trapped debris to easily clear. The steel buffer body is protected by a slick salt bath nitride finish for smoother cycling and resistance to corrosion.
Quick change barrel systems for AR-15’s are nothing new. I enjoy the ingenuity and engineering that goes into most them.Today’s entry is the Pantheon Arms DOLOS AR-15 Takedown Kit. The DOLOS is one of the most interesting approaches I have seen to date. Basically once an AR upper and barrel are configured for the takedown kit its a matter of pushing a button and rotating the handguard. (Watch the video at the bottom of the page to see the Pantheon DOLOS takedown kit in action.) What I like most about this AR-15 Take-down kit is it’s ability to use non proprietary handguards from quite a few manufacturers listed below.
Extra lock down collars are available to add additional barrels to an upper.
Note – Bolts should not be used with more than one barrel. Get an AR-15 bolt for each barrel you plan on using.
The DOLOS Takedown Kit allows for quick separation of the handguard & barrel from the upper receiver, resulting in an extremely compact & convenient package. Kits simply attaches to your per-existing AR-15 barrel and is compatible with standard YHM free float handguards (Diamond, Tactical, etc). System works with standard AR-15 gas tubes and gas blocks. Once installed, user simply has to retract the bolt, insert the handguard, barrel & kit onto the upper receiver, turn the system 1/3 of a turn and you have an assembled upper receiver. Kit works great in conjunction with a LAW Tactical Folder for an extremely compact disassembled firearm.
The Dolos is a rapid deployment and takedown system (RDTS) for the AR15. Dolos enables discreet, concealed carry and rapid deployment of any Milspec AR15, extending the capability of any AR15 through its detachable barrel technology.
Benefits of Dolos include:
Whether you want to put your AR15 into a backpack / messenger bag for covert carry, use multiple barrels with various calibers, or create your own genuine can of Whoop Ass, Dolos is your cost effective solution.
