PKM / UKM Lightweight Outer Barrels with Integrated Front Sight
Drop the bulk. Keep the bite. Authenticity meets innovation.
The Bull Craft PKM / UKM Lightweight Outer Barrels are engineered to dramatically reduce front-end weight while preserving the aggressive presence and rugged performance these platforms are known for. Whether you’re building a compact PKM setup or a full-length UKM-2000-inspired configuration, these barrels deliver serious weight savings, durability, and precision.
Manufactured from SLS-fused Nylon PA12, each barrel is designed for strength, dimensional stability, and real-world reliability. Select models feature functional fluting, engineered to properly cool the SLS print during production and prevent warping — while adding an aggressive, modern aesthetic. Still tough. Still badass. Now better looking too.
All variants include an integrated front sight for reliable target acquisition and are reinforced with CNC-machined aluminum barrel threading components for precision fitment and long-term durability.

Pkm barrel
Wanted a lighter barrel for the heavy a&k pkm. Decided to pull the plug on this and no regrets. Sturdy, threads are clean for flashhiders. Just a solid choice to lighten the gun.

Awesome quality, low price
I have been anticipating the release of this for a while. I even remember asking for these to be made in a post on Instagram awhile back. I wasn't expecting the level of quality that I got when when I ordered this. This part is simple to install with the 2 screws in front of the hop up screw on the original barrel, and makes a huge difference in weight. The part measure up to about the gas block on the stock pkm barrel, so expect that difference when you order. (You can also just contact BCI and they will work with you). My stock barrel/gas block were a little wobbly, and this new part cleaned that up. Overall, I really can't recommend this part enough. 5/5 - customer service is awesome. Quality is almost indistinguishable from a manufactured polymer. Looks great and has a awesome finish, plus good weight savings.
