TacFire Stainless Steel Long Buffer — 7.0 oz | Maximum Control for PCC & Suppressed Carbine Tuning (SKU MAR044-7.0 | UPC 659725017420)
Get your recoil system under control with the TacFire Stainless Steel Long Buffer — 7.0 oz. This heavy, long-length carbine buffer is purpose-built for AR-pattern pistol-caliber carbines (PCC) and suppressed/over-gassed 5.56/.223 setups that need extra mass to slow bolt speed, reduce parts wear, and flatten recoil impulse. Machined from stainless steel for durability and corrosion resistance, MAR044-7.0 drops into a carbine-length receiver extension and immediately helps stabilize ejection, protect bolt catches, and calm dot bounce for faster, cleaner strings.
Fitment Snapshot: For carbine-length buffer tubes only. A top choice for 9mm/.40/.45 blowback PCCs and suppressed 5.56/.223 rifles that benefit from heavier buffers. Not for rifle-length A2 systems.
Why Choose a 7 oz Long Buffer?
Maximum bolt-speed control: The extra mass of a 7.0 oz buffer slows the cycle in straight-blowback PCCs, reducing slam and extending component life—especially the bolt catch and receiver extension.
Flatter shooting, less bounce: Heavier buffers deliver a smoother recoil pulse, helping you track the dot or reticle through rapid fire for quicker split times and better transitions.
Stainless steel strength: Corrosion-resistant body stands up to moisture, solvents, and high round counts—perfect for training guns and match rigs.
Improved reliability when tuned: Pair with the correct spring for consistent ejection and dependable LRBHO (last-round bolt hold open) in compatible lowers and mag systems.
Drop-in convenience: No gunsmith required. Swap into a carbine-length extension and start tuning immediately.
Ideal Use Cases
PCC (9mm/.40/.45) blowback ARs: Heavier/long buffers are widely recommended to manage bolt velocity and protect internals.
Suppressed 5.56/.223 carbines: Extra mass helps offset increased carrier speed from back pressure.
Short gas / hard-running uppers: Smooth out SBR-length or over-gassed configurations for more control and less wear.
Competition & training: A calmer impulse improves shot cadence and consistency during high-round-count sessions.
Key Features at a Glance
Type: Long-length heavy carbine buffer
Weight: 7.0 ounces
Material: Stainless steel body for durability and corrosion resistance
Compatibility: Carbine-length receiver extensions (AR-pattern)
Best With: PCC blowback builds and suppressed/over-gassed 5.56/.223 tuning
Model/SKU: TacFire MAR044-7.0
UPC: 659725017420
Finish/Color: Natural stainless
Why “long” matters: Extended carbine buffers limit over-travel in blowback systems, improving feeding/ejection timing and helping prevent bolt-catch damage.
Tuning Tips (Best Practices)
Match the spring: Start with a quality carbine or PCC-specific spring. If ejection is weak, consider lighter spring or gas; if brass launches excessively far, heavier spring/buffer can help.
Test your ammo: Validate function with your primary match/duty loads, then spot-check with secondary loads for reliability.
Verify LRBHO (PCC): Ensure your lower or mag block supports bolt hold-open; adjust buffer/spring if lock-back is inconsistent.
Suppressor setups: Heavier buffers are a great start; pair with adjustable gas (where applicable) for optimal results in 5.56.
Watch wear points: After initial range sessions, inspect the bolt catch, cam path, and receiver extension for signs of over-speed. Proper tuning should reduce these.
Installation Overview
Unload & clear the firearm.
Remove the existing buffer and spring from the carbine-length tube.
Insert your chosen carbine/PCC spring and the TacFire 7.0 oz long buffer.
Function test for smooth cycling and bolt hold-open (with an empty mag).
Range verify with standard ammo; note ejection pattern and lock-back consistency.

FAQs
Q: Is this only for 9mm PCC?
A: No. While superb in blowback PCCs, it also helps suppressed or over-gassed 5.56/.223 carbines when paired with the correct spring/gas setup.
Q: Will it fit a rifle-length A2 tube?
A: No. This buffer is for carbine-length extensions only. Use a rifle-length buffer in A2 stocks.
Q: Do I need to change my spring?
A: Often yes. The best results come from tuning spring rate to your ammo and platform. Many PCCs prefer a dedicated PCC spring.
Q: Can a heavy buffer hurt reliability?
A: When properly tuned, heavier buffers improve reliability by moderating bolt speed and reducing bounce. Always verify ejection and lock-back.
Q: Does stainless require special care?
A: Stainless resists corrosion, but basic maintenance—light oil and periodic inspection—keeps everything running smoothly.
