Hey, im new here so for give me if this has been asked, im looking at a bushmaster predator, http://www.bushmaster.com/catalog_xm15_PCWVMS20FPRED8.asp i plan on putting some nice glass on it however i also wanted to have iron sights with it. What i was wondering is if i can change the gasblock that is on it and put in a RRA gas block sight base http://www.rockriverarms.com/index.cfm?fuseaction=category.display&category_id=375 IS this easy to do? Also how would my rear sight system work with the scope risers that are on the rifle? (im not sure if there removeable) Please enlighten me, any info is good...

The risers are removeable.

The FSB switch can be done, but, I'd order the predator upper without a pinned gas block.

A BUIS should fit the weapon just fine, even with a scope in place.

Suggestion: Get a LaRue or GG&G QD scope mount, otherwise having back-up irons is kind of a waste of time & money.

Better than I can shoot. Under 1", at least.

Have you looked at the RRA Predator Pursuit?

Yea i have looked at it online, i actually would rather have it but no shops around here have any in stock nor any complete uppers and they all said the wait is at least 3 months. i can get the bushmaster predator for 999.

Hello Boomhower:

Welcome to the Forum!

I believe your Predator is much like my Stainless Varminter. I think they both use the same  V Match milled sight base/gas block. Bushmaster advertises the following product online. I don't know if this is the sort of thing you were looking for:

http://www.bushmaster.com/products.asp?cat=19

B.M.A.S. Front Flip Sight for V Match Rifles and Carbines
A high quality front sight that clamps around the V Match milled sight base/gas block - designed to be used with any open iron rear sight. This patent pending Front Flip Sight is machined from aircraft aluminum with an anodized finish, installs with an Allen wrench, locks up or down with a push button and is elevation adjustable. A standard front sight post is included, and the base is drilled and tapped for our B.M.A.S. Sling Swivel Stud (see YHM-9364 below).  Price: $106.50  Part No: YHM-9360K

You could call or email Bushmaster Customer Service. They are very friendly and helpful people and can probably tell you if this will work for your Predator. If so, it should save ou the trouble of swapping out the gas block...

As a previous poster indicated, if you are going to ORDER the rifle from Bushmaster, you could simply order the desired gas block from them at the same time. They will credit the V Match milled sight base to your account, charge you for the preferred gas block/front sight, and probably install and test-fire the rifle for you at no extra charge. I have had VERY good experiences with Bushmaster customer support...

Again, welcome to the Forum. I hope this post is helpful.
