I remember hearing the phrase “don’t put glass on a battle rifle” because it was pretty common in the 1990’s to not have 308 optics that held up to what the FAL and G3 rifles were doing to them.   Many of the battle rifles that were designed in the 1950s and later did not have optics meant for them.  Optics never caught up to combat durability until probable the ACOG  came out.    Even after that the ability to properly mount something like that on an FAL or a G3 style rifle was very difficult.

DSArms still makes the best FAL in my opinion and I own several of them but I have had some issues with the mounts they sell.  After about 3000rds i had a mount come loose and it’s caused me to second guess the design.  The one thing I really like about Trijicon Rifle Scopes especially the Trijicon ACOG is that they can be much easier to mount.   The Trijicon ACOG has a mount that can be screwed on and there is no worry about the reticle turning on you.  Everything will be level right from the get go.  Loctite still has to go on everything that screwd in, but it’s nice to not have to worry about that one thing.
