Superior flip up sight
The first military SPR Mk.12 mod.0 came out with the Precision Reflex flip up front sight. These are superior sights, not cheap stuff. There sights are superior, if they were chosen for Naval Special Forces, they had to be. They are easy to install and there is another version with set screws. As to which one is the best is really entirely up to you, many people swear by the crossbolt because they offer for accuracy without the fuse of having to machine flats on your barrel. I have both and I think I like the crossbolt better.
used for a faux dissipator build
Sturdy, well made and idiot proof.
I used this with a faux Dissipator build and the cross bolts are idiot proof.
Pairs well with a number of rear sights.
Not much else to say here.
Whether you’re using the gas or not the thing is bombproof

Great sight!!
Love this front sight gas block!! Cross bolt is rugged and will handle a beating while maintaining zero. Necessity for Mk12 build!! Got it in 4 days!! Flip up push button is strong. Have the adjustable front sight, so I don’t need a tool to adjust. Very handy in the field if expedience is the Priority.
Best Used for:
- Mk 12 clone
Would recommend: Yes

Solid barrel mounted front sight option
Grabbed this front sight gas block for a recent mk12 inspired build. Mounted it to a stainless BA SPR barrel. Sight itself and folding mechanism seem very sturdy and high quality. I'm generally a fan of taper pinned front sight bases but after installing this I'd be shocked if it was ever a problem outside the most extreme circumstances. OP had one of the best prices around, but the shipping they use is crazy. Product itself is good to go though.
Would recommend: Yes
Great sight
Easy to install and provides an amazing sight picture. The product does not come with a gas tube pin. The finish is also impeccable. Would recommend to all my friends. Inserting Random word because you have to write a minimum of 200 characters

Great Flip Up Sight
This is a great flip up iron sight/gas block if you're trying to be clone correct or if you just like flip up iron sights. It'll replace a standard A2 post and it's pretty slick. I have it fit inside of a FSP rail (I have both the KAC MRE and Centurion C4 FSP).
Would recommend: Yes

Heavy duty sight
Premium iron backup sight. Built military tough so I know it’ll handle anything I can throw at it. Easy install. Sight picture is better than any backup sight I’ve ever used. Installed an a 2013 Colt LE6920. Now I need to shot around for a rear sight of equal quality. Opticsplanet shipped 2 day delivery at their cost. Arrived at my door on third business day. Good transaction.
Pros:
- Tough construction, awesome sight picture. Easy instal following included instructions.
Cons:
- Finding a rear sight of equal quality
Would recommend: Yes
PRI Flip Up Front Sight/Gas Block, .750", cross bolt
This is a great flip up front/gas block combo. Must have the correct length on gas journal (1.9") for it to clamp correctly. Cross bolt system makes the unit rock solid. Gives your rifle an old school look like a Mk12, Mod O. Must use the correct length free float handguard to work/look right.
Pros:
- solid mounting system
- best flip up front sight/gas block combo
Cons:
- None
Best Used for:
- AR-15 with .750" gas journal that is 1.9" long
Would recommend: Yes

Solid front sight gas block
This is one of the most rigid and well made front sights I've seen. I'm in the middle of build a m4a1 and this sight sits perfectly and function as good as any high end sight should. After looking at gas block plus front sight prices this was a no brainer.
Best Used for:
- Carbine and mid length handguards
Would recommend: Yes
