  • Alloy construction
  • Screw secured pins
  • For Specna Arms M4/AR-15 AEGs

If you've lost a body pin in the field, the Specna Arms Body Pin Set for M4/AR-15 AEGs is what you need to make it right. This set includes front and rear screw-secured receiver pins and a trigger/gearbox pin, all constructed from alloy. The perk of screw secured pins is that, unlike standard friction-fitted pins, they'll never slide out in the field, provided you tighten them down and regularly ensure they're still firm.

Compatibility-wise, these pins are designed for Specna Arms M4/AR-15 AEG replicas but may also work with other brands. We advise proceeding with caution when installing these pins, especially in non-Specna receivers. When working with Airsoft externals, use as little force as possible to get the job done and avoid hammering them in like a caveman!

  • Speed up reloads significantly
  • For TM Hi-Capa style polymer grips

If you're building up your Hi-Capa with speed as the objective, you need the Airsoft Masterpiece DVC Flared Magwell for Hi-Capa GBB Pistols! Styled after the real steel DVC flared magazine well, this extension to the base of your grip helps guide your magazines in during an adrenaline-fueled reload, whether you're on the skirmish field or cleaning a course of fire in an IPSC competition.

A flared magazine well extension also enables "eyes-up" reloads so you can continue to scan for the next target as you bring your pistol back into action, an essential skill to have if you aim to be the fastest shooter you can. Compatibility-wise, this magwell is for the original Tokyo Marui Hi-Capa polymer frame and should fit most similar designs but won't work with aluminium frames or alternative frame designs. For a touch of style with a side of speed, you can't ask for better than the DVC Flared Magwell for Hi-Capa GBB Pistols from Airsoft Masterpiece!

This set includes the upper and lower receiver, fire selector switch and front receiver pin, available in high density polymer or alloy construction. If you're working on a lightweight build, the polymer version is ideal. If you want weight and realism, you want the metal version!

Styling-wise, this receiver set is Delta's own design, inspired by real steel "Billet" receivers found on high-end, ultra-modern real steel AR builds. The trigger guard is enlarged and built-in, improving strength when compared to milspec receiver designs, in line with the latest real steel ARs hitting the market. As we might expect, we are treated to a 20mm Picatinny receiver rail running along the top, ready for a red dot sight, scope or iron sights. 

If you're building from scratch, you will need a charging handle, magazine release, dust cover and mock rear pin to complete the receiver itself, along with your internals and pistol grip. While we can make no guarantees, parts from most other brands should fit this receiver without issues. Whether you need a bargain receiver for a scratch build or want to change the build style of an existing M4/AR-15 AEG, the Delta Armory Receiver Set for M4/AR-15 AEG will do the trick!
