Was wondering if anyone has used the colossic bolt lock or compared it to the JB bolt lock. Emailed colossic about how it works.
"the 10/22 Bolt Lock gives a Ruger 10/22 a select fire option of semi-auto and bolt action.
To switch from semi-auto to bolt action, press the 10/22 Bolt Lock against the bolt, it will click and stay in place.
To switch from bolt action to semi-auto, squeeze the 10/22 Bolt Lock handle with the charging handle.
In order to cycle a round while in the bolt action position, squeeze the charging handle with the 10/22 Bolt Lock handle to release the lock, pull back to eject the previous round, release / push forward to chamber a new round, and finally push the lock back into position as you move your hand to the trigger handle (if your right handed) or to the stock (if your left handed). It is a very natural motion similar to manually chambering a new round from a fresh clip.
We have tested the action with Remington Golden Bullet, Remington Subsonic, and Aguila SSS ammo. The testing was preformed with a Ruger 10/22 stainless steel carbine with a standard stock and a Tactical Innovations 16.5" 1:9 twist stainless steel factory taper barrel and stock 10 round magazines.
We can not guarantee if you use a custom stock or a custom receiver this bolt lock will work. The size of the ejection port is critical as well as clearance directly behind the ejection port.
Installation of the 10/22 Bolt Lock is relatively easy, similar to replacing the charging handle / spring assembly. First, remove the stock. Second, remove the trigger assembly. Third, remove the bolt stop pin. Fourth, depress the charging handle and remove the bolt. Fifth, replace the existing charging handle with the new 10/22 Bolt Lock (must be inserted through the ejection port). Sixth, reverse steps and reassemble with new 10/22 Bolt Lock in the position where the old charging handle / spring assembly was. No machining is required and it is easy to replace the 10/22 Bolt Lock with the original charging handle / spring assembly to return to the stock configuration."
also in a second email "The 10/22 Bolt Lock forms a block between the receiver and the charging handle to keep it from moving backwards, then the bolt pushes against the now fixed charging handle. We don't notice any movement in the bolt. We haven't used any precise measuring tools to check this though.
We tested Aguila SSS on a standard bench rest at 25 yards (not using blocks / vices). Firing 5 rounds bolt locked and 5 rounds semi-auto. With the bolt locked the grouping was 0.90 inches across and with semi-auto the the grouping was 1.13 inches across and centered 0.26 inches lower. With our measuring equipment the noise decreased by average of 9.4 Db."
Sound interesting and easier to use than the JG bolt lock. any experience with it or compared it with JG? The website is http://colossic.com/defenseproduct.html

I emailed silencer research about it and possible testing and am anticipating seeing it in the near future.
