"Solid bolt.


-Price (compared to NPAS Kit to raise your FPS)
-Super easy to install like all LM4 Bolts, and can just be replaced for a CQB bolt. Save your money and stay away froim the NPAS Bolt. This thing is great to switch out with the stock bolt.

"Wow! This damn bolt makes my rifle fire so crisp and hard as hell! damn thing was shooting at 500fps with Nuprol red gas (obviously It was shooting way to hot so I switched to Nuprol green gas, wich works great at around 397-405fps) Very great bolt for the KWA LM4 and I recommend it to every LM4 owner!
