NcStar AR15 Rifle Length Quadrail Handguard (MAR4L)

 (9 customer reviews)

As the title mentions, I'm a beginner to AR 15 modification (starting off with a full length rifle).

I removed the old hand guards and installed the NcStar without the use of the hand guard removal tool available from other sellers. It wasn't easy or quick, but it can be done. I would however recommend you get one or make one yourself.

It isn't readily obvious from the picture, but this hand guard is wider than it is tall causing it to be somewhat awkward to hold bare, but I attached a fore grip to the rails so it the disparity didn't mean much to me.

Reviewers on other sites, MidwayUSA and others, mention that they've experienced some bowing when joining the two halves together with the supplied bolts. I checked with a level and didn't notice anything. Maybe somebody is over tightening the bolts and not wanting to admit it?

Also, there is no secondary heat shield between the hand guard and the barrel. I haven't fired it yet with the hand...Read more

The rail system is a wonderful modification to handle almost all of your AR accessories. This full length hand guard arrived in it's box, and I eagerly anticipated installing it. Rule of thumb installing after market hand guards: use the hand guard tool, or a buddy to help! These rail systems are aluminum, so they will scratch if you are careless. Second, you'll be using the supplied wrench to install and tighten the screws of the hand guards together. The screws seem to be a wee bit long, and after securing the guards, are visible. They don't get in the way of using the rails, but a star off for that. The disappointment was that this did not come with rail covers: hence deduction of two stars. Stay Safe, and keep it pointed down range

Bought this for my 20+ year old Colt AR-15. Figured it needed to be brought up to today's standards. Went on fairly easy. Looks great. Excepted my bipod with no issues. Very high quality materials and construction.
