| Anyone have any info on the old Crossfire 9mm mag blocks? |
The CrossFire 9mm magwell conversion block is ALL steel and it is placed into the magwell through the bottom upwards. A ball detent on the front of the block has tension that holds it into place in the magwell. It also has an area on the side of the block where the magazine release fits into and holds it into place. When you release the magazine release button, it allows the magazine to drop free but still holds the block into place. The feed ramp allows just about any size of 9mm to be used and it is a part of the block. Is the feed ramp welded or machined to the block itself, I'm not sure since I don't have the block in front of me to look at. I've never had a round jam or FTF due to the the feed ramp. The ejector is held in the block by a pin I believe, so it can be replaced if need be. My ejector rides "nearly" side by side with my bolt without actually touching the bolt, and this has given me NEAR flawless performance at ejecting cases. This is critical and on some setups may need to be tweaked. One of the best features on the CrossFire is holding the bolt open on the last round fired WHEN using Colt mags. It really improves your ability to perform better at subgun shoots with this feature. The only problems I've ever really had was due to bad or damaged ammo but that is no fault of the CrossFire block. I hope this helps.

-------------------------------------------------------------------------------- Quoted: That block looks like it has a means of pushing up the standard/223 bolt catch. Looks like a good idea to me. No other mag blocks have that? Why not? -------------------------------------------------------------------------------- Colt and the now defunct Tacblock have it as well. My experience with the Crossfire and Tackblock is that they can fall out when doing a fast mag change. The Colt block cinches in place tightly and doesn't fall out. No experience with the Hahn bottom loader. |
However, they can be difficult to get sometimes. |
