Retro Arms, a well-known Czech manufacturer of parts for replica, has recently prepared several new products.
Starting with internal parts, the CNC Hop-Up Chamber AR-15 Ultra is available in pre-order. The design is made of milled 7075 aluminum and is a development version of the Basic and Pro models. The main new functionality introduced to the chamber is the ability to adjust it along the barrel length (front to back) by 0.2 mm for the best possible fit with magazines.
Stabilization is achieved by additional pads. The C-clip has also been redesigned, being made of POM and it also has a centering barrel nut.
The whole thing guarantees an even more stable construction and no vertical movement. The BB feeding channel in the chamber has also been changed, while maintaining the adjustable turret. The new chamber is not yet available, and a pre-orders are being conducted on the manufacturer's website at a price of 2490 Czech crowns, or about PLN 430.
Retro Arms is also expanding its range of receivers with the new generation of the CNC AR-15 receiverC models. They are made of EN AW 7075 T651 aluminum are still protected with a hard anode. The new generation has introduced a whole range of changes compared to the previous one, and these include: changes to the dimensions of the guide and grip socket for greater compatibility, changed geometry around the magazine release lever to avoid accidental magazine release, changes around the fire selector sockets, new pin placement, reduced clearances between the upper and lower receivers and many other major and minor changes. The new receivers also come with a full set of necessary accessories, from pins to adapters and screws. You can choose between the classic version at the price of CZK 7,790 and the skeletonized version at the price of CZK 8,590. Both are available for purchase at the manufacturer's website.
Another receiver currently being worked on is the CNC AR-15 NGRS, a variant designed for Tokyo Marui's Next Generation Recoil System replicas.
