SBR P90 Barrel Specifications From Gemtech

[TurkeyLeg]

Edited by MP
These measurements are per Gemtech


-- i now have the exact measurements of the FN P90 barrel from Gemtech, for anyone who needs them.

the barrel OAL used in the measured sample is 10 13/36 (10.406). it is NOT 10.3 inches, dont cut your barrel to that length.

the distance from the crown to the last thread is .980 inches. the muzzle step down diameter is .400 inches for a length of .170 inches. you can use a larger or smaller diameter if you wish, but .400 will fit every current adapter or hider designed for the P90, including my Gemtech Bi Lock. supposedly, there is a relief machined after the final thread.

for those who might not know, the factory threads are 12mm x 1 left hand.

i hope this helps anyone who needs it. as far as i can tell, this is the first time the exact dimensions have been posted on the net. thanks FNForum.net.

Thanks for the information. Exact measurements are always preferable.

No further discussion needed. Thread locked. Stickied.

They way it has been explained to me...

FNH will not release the exact dimensions as it is intellectual property. So at best Gemtech's answer is what they cut them to.

As directed earlier if the barrel is cut to 10.3 plus .005" it will not ruin your barrel. Anywhere between 10.3 and 10.4 is the accepted standard.
