Just picked up a Hy-Tech block.  I can't insert the block far enough into the magwell for the mag catch to lock it.  I can open the upper/lower at the rear take down pin and insert the block until it locks. I can then close the upper/lower, but it's a very tight fit.  There seems to be a lot of pressure on the mag catch once it's closed.  So much so that I can't press the mag release button to release the block.  I have to separate the two halves again to release the block.

I'm a little concerned with that much pressure on the mag release and between the upper and lower.  Has anyone else experienced this with the Hy-Tech?  If so, did it cause any problems?

Thanks for your input.

Mine was hitting the inside of the upper. I had to chamfer both sides of the block to get the upper to close. It doesn't take much.

I thought that maybe it was hitting in that area.  You've saved me a lot of troubleshooting... Thanks!

ETA: Where you able to insert the block into the locked position without having to open the upper/lower after you did this mod?

Mine is snug when closing since April 2003... the mild downward pressure keeps you from readily pushing the AR mag button and dropping the block.

I still open mine and install the block, then close the upper.  Use the snug fit to your advantage to eliminate the wiggle loosness normally found on the AR/M16 family upper-lower fit, makes the rifle more 1 piece like..

Yep.  I think it was designed this way to keep you from dumping the block with the "standard" mag release button.

Without the block, the Spikes lower and RRA upper did have the normal amount of looseness.  I must admit I was happy to see things tightened up when I inserted the block.  My concern was for the amount of pressure on the mag catch.  But, I guess that's easy enough to replace.
