The fixed barrel mount is for firearms with just that... Fixed barrels. The booster is for semi auto firearms like hks glocks etc. they need the booster to aid in reliability.What's the difference between a Fixed Barrel Mount vs a Recoil Booster??
<< Total Noob.
Still debating about ordering the QMF-2 or wait til my Isis22 come in and play with it first and then decide. If I get on the QMF-45 as well... that's more than a grand I'll be spending and wont see any "result" or "product" for at least six months...
Not sure how the GF will feel about that. I'll have to convince her tomorrow.
An example of the fixed barrel is your ruger 22s , ar15s and unique guns like the hk p9s.
