For true blue shooters, learning how to aim with iron sights is a necessary skill to learn. Red dot sights may be well and good, but sometimes they go up at the most inconvenient times. By learning how to use iron sights, shooters don’t have to spray their bullets all over the place.
The problem with these backup sights is that sometimes they can cost a lot of money. Buying cheap, on the other hand, may result in a low quality product. But with the MAGPUL Gen 2 Front Back Up Sight MBUS, you can actually pay a small price and get huge benefits.
One of the reasons for the low price is that it is made of polymer, albeit it is impact resistant. Flipping up the sight is easy enough by pressing the top or activating from the side. The spring tension also locks it down, but with enough give upon impact. The protective wings offer additional protection.
The MAGPUL Gen 2 Front Back Up Sight MBUS is compatible with most MIL-STD-1913 Picatinny/STANAG 4694 railed hand guards. It also offers same height-over-bore as standard A2 irons.
The elevation adjustment tool is part of the purchase normally, but shooters can use just about any aftermarket A2 front sight adjustment tool.
Pros and Cons
The MAGPUL Gen 2 Front Back Up Sight MBUS comes with a very reasonable—in fact, a very affordable—price tag, yet somehow it also comes in a very high quality. The polymer may not be technically “iron”, but it’s virtually as tough and it’s lighter as well. It will last for quite a while.
This sight is very easy to mount, and zeroing it doesn’t take a lot of time and effort. The spring tension is great too. Snapping up the sight is quick and firm, but it offers enough give when it hits something. The accuracy is also undeniable, and it offers quite a relief if a shooter’s red dot battery dies at an inopportune time.
But of course it’s not absolutely perfect. For one, it can’t be mounted to a railed gas block because of the heat. It also has to be mounted to a railed fore end that’s on the same plane as the receiver rail. For this reason, this Magpul front sight won’t work with MOE hand guards.
The MAGPUL Gen 2 Front Back Up Sight MBUS is a piece of compelling evidence that superior quality doesn’t have to be expensive at all.
