Worked great for my application

by -

Used this to cover the quad rails on my LWRC IC-A2. It covered all sharp edges and was easily trimmed around my QD sections. They fit securely but can be easily removed if needed. Overall very well made product.

Excellent Rail Protectors!

I've used these many times on all my AR's (9) and these are fantastic at what they do - protect your top rail from damage as well as your fingers! Best price too! Great Ergo product, thanks Primary Arms!

Excellent product

Used these to cover the sharp edges of my LWRC Quad rail handguards. It did the job and does not wiggle around at all. It was also very easy to trim for the built in QD sling
Points too. I’m on my third set of these.

These are exactly the same as Magpul pic-rail ladder covers...they are from the same factory as the Magpie model.

These fit perfectly, and are very secure. Came from the same source that the Magpul item come from. I bought both, taking a chance on these due to price. I compared the Magpul to these and found them to be identically marked from the manufacturer. Save some cash and buy these.

Works well as expected.

These fit nice and tight and have a good feel to them. They should give you 4 due to the cost but that’s not PA fault. Fast shipping arrived as expected
