PLEASE NOTE BEFORE ORDERING: We hold a tight +.001"/-.001" tolerance on this part. Unfortunately, some of the more recent BRN bolts do not. The mounting socket dimensions on the BRN bolts are not consistent, however it is a small percentage of bolts and this product will fit 95% of them. How do we know? Because we've sold over 1500 of these to date (as of 07/2024) with less than a handful returned that did not fit. If you get one and it doesn't fit, please return it at no charge. It is not a defective part, this is a BRN issue. Please do not try to modify it, please do not go online blasting A3 Tactical, as this is not an A3 Tactical quality control issue, it is variance in the BRN bolts. |
The BRN-180 line of bufferless upper receivers was designed to mimic the original AR-180/AR-18 with it's right-side offset and reciprocating charging handle. While some may appreciate the period-correct look and function of the charging handle, a lot of people prefer a more modern option. A3 Tactical has come up with various options to meet this demand.
If you don't mind a reciprocating charging handle but just prefer a nicer handle to grab, we have 2 options available to suit your needs. These are simple 10 minute upgrades.
For those that want a more modern upgrade, we also have a non-reciprocating version of the handle. This unique upgrade features a forward mounted guide rail and handle that does not move with the bolt. Simply replace your charging handle with our steel bolt adapter, mount the guide to your rail, and install your handle. The entire upgrade can be done in 15 minutes.
The high-tolerance bolt adapters are manufactured from 4140 steel. Only the low-profile adapter reciprocates with the bolt. The charging handle itself remains on the guide and stays latched via a tensioned ball detent. All components machined from 7075 aluminum and hard anodized. Your choice of grooved round handle, or finger-notch handle.
