Loose mag fit on 5. 7 builds

Review by Steven R. on 9 Jul 2025 review stating Loose mag fit on 5. 7 builds
If you build a 5. 7 be prepared for a VERY loose fitting magazine. I cured that with a cut off brass machine screw I threaded into a drilled and tapped hole in the front edge of the mag. Now she's tight. RANIER had the best price and picked up the ball when USPS lost my package (again, bastards), Someone will own a fine custom gun soon. Wish I could post pics.

A Functional Flash Suppressor

Review by Beau W. on 9 Jul 2025 review stating A Functional Flash Suppressor
You can't even see a flash from the shooter's perspective firing at dusk through a . 357 lever gun. , and it's a rosebud to anyone else. I like it a lot.

18" mod 2 223 wylde ultramatch

Review by Jason Y. on 8 Jul 2025 review stating 18" mod 2 223 wylde ultramatch
Okay so barrel is broken in. This barrel is unbelievably accurate. Printed groups at 100,300,500 today and the verdict is in. WOW! 100 yards 3 shot measured 3/8", 300 yard 3 shot 7/8" and 500 yard measured under 2". Absolutely incredible. More accurate that most big bolt guns.

RAINIER ARMS AR-15 FORGED LOWER RECEIVER

Review by Raul on 8 Jul 2025 review stating RAINIER ARMS AR-15 FORGED LOWER RECEIVER
RAINIER ARMS AR-15 FORGED LOWER RECEIVER - hands down one of the tightest fitting receiver when paired with Rainier Arms forged upper receiver! I had to use a mallet to take it apart! Anodizing was perfect with deep black finish! Would definitely recommend!
