Nice looking rail and great lockup - UTG Pro M-LOK AR15 10in Ultra Slim Free Float Handguard

This is the 2nd UTG Pro rail I’ve used and this one is just as nice and solid as my first one. In my opinion, these rails are well worth the price and will fit perfectly on a standard forged mil-spec upper receiver. That being said…I bought this for my PSA KS-47 and it will not fit correctly without a slight modification to the anti-rotation tab opening. I had to use a dremel to make the rail opening wide enough to center and fit on the upper receiver. I didn’t have to remove much material to get the rail to fit and I was pleased with the final results. Still a great rail but if you want to use it on a PSA KS-47 or a billet upper receiver, you may have to modify the rail to fit.
