To be honest I was not expecting much at this price point. I am happy to say I was wrong. This product is well worth your time and money.

measure first!

Great product, great price point. Measure complete build before ordering your quad rail. I ordered off of barrel size before completing my build so I was a little off on length needed.

The items are good and at good prices and of good quality but shipping by boat is too slow

9" Quad Rail

Ordered this for my personal build. Build quality was great, everything fit together nicely and very few machining burrs like other companies. Installation was a breeze and everything torqued down fine. Only problem I see is the handguard has some play left and right. I can only assume that it's due to the two locking lugs in the barrel nut. No matter how I adjust it there's about 1/32 of movement after torquing. If you use a sight on your receiver this shouldn't matter but if you plan to attach a front sight to the handguard it's going to be cause for concern.

4” rail

Great item for the price point, only issue is it didn’t fit my pistol build with 7” barrel with an A2 front sight tower.

Good price, wrong end cap

The price is the best you can find. Unfortunately it was paired with the wrong end cap and they wouldn't let me return it.
